14:22-14:38 Summary
Glycolysis takes place in the cytoplasm. In glycolysis, glucose is broken down into pyruvate, and then into Acetyl CoA. The process generates a net profit of two ATP, plus some NADH and carbon dioxide.
In the Krebs Cycle within the mitochondrial matrix, the Acetyl CoA is added to Oxaloacetate in a cyclical set of reactions. These reactions generate a few more ATP plus a load of NADH and FADH2.
Finally, the Electron Transport Chain creates a proton gradient across the membrane separating the mitochondrial matrix from the intermembrane space. The proton gradient is created with products transported by NADH and FADH2. The gradient then forces protons through a protein called ATP Synthase, recharging many molecules of ATP. Oxygen functions as the final electron acceptor to absorb the electrons that are exiting the Electron Transport Chain.

I loved it!
We need more mnemonics like that. So much easier to remember!!
Definitely caught me off guard on that Kreb's Cycle memorization saying lmdaoooo
And now you'll NEVER forget the steps of the Kreb's Cycle, will you? ; ) Sending love and best wishes from Boston! -BOGO
Same 😂😂😂
I was like... damn, bio just got interesting lol
LOL I laughed so loud my husband said "I thought you were in the computer studying"
Me too! My jaw literally dropped and I started DYINGG. It will definately stick with me though 🤣
I had to pause the video, I was laughing way to hard at the Krebs cycle thing, I def remember it though lmaooo
Glad you got a kick out of it, it's gotten me into a LOAD of trouble haha Love, BOGO
Look no further: Best video on Kreb's Cycle. I love Khan Academy, but this one here is better than theirs on the subject.

I don't know why college teachers can't teach like this?
By the way, thanks for helping.
Ha! Even I can't teach like this. This video was outlined, scripted, revised, animated, revised, recorded, and revised again before I published it. When you're teaching "live" you don't get to do that stuff. That being said, I always "outline" what I want to teach with a set of notes for myself, some key examples I want to make sure to bring up, and a few really good "scripted" questions that begin with a question every student in the room can answer. When I do that, I can focus on making sure everyone is on the same page, managing any problematic behavior, and tweaking the explanations on the fly rather than wondering "what the heck is my next line?".
That being said, most college teachers don't do that. I really noticed it when I went to grad school after almost a decade of teaching; the teaching standard was pretty lousy as a whole, even at Harvard. the heavy emphasis on research selects against those who put more effort into teaching. Often, they're brilliant thinkers and do-ers, but not good explainers. Reminds me of how the best athletes are not necessarily the best coaches; they can so easily do the skills without thinking that it's really hard for them to break it down for a novice learner. Thank you for coming to my TED Talk! -BOGO
@@BOGObiology sorry, that was a bit rude.
@@KJ00062 Eh, I don't think it was rude, I think it's honest. But I think it also highlights the fact that universities generally don't prioritize or reward good teaching. The emphasis is almost exclusively on research. So many of my professors were brilliant researchers but couldn't explain anything. It often reminded me of a superstar professional athlete trying to coach a high school sports team; it's so intuitive for them that they can't place themselves in the shoes of someone who is less skillful. Sigh. Maybe someday things will be different!
I've been trying to wrap my head around how cellular respiration worked (learning about metabolism) for THREE straight years. Only after watching this video did it finally click and make sense. THANK YOU SO MUCH FOR YOUR CONTENT! I had no clue that these three processes were connected, THAT'S how lost I've been. Now I enthusiastically told my mom the whole process without having to look at my notes (the basics of them of course). - Current A&P college student

To this old Englishman's ears (retired electron microscopist) You have really nice voice. BTW I'm looking for resources to teach my grand-kids cell biology.
Aren't the "Prep Steps" actually called Link Reaction and I learned that they were already separate from the Krebs Cycle
Good question! There are a bunch of names for the same thing; when I learned these steps, they didn't have a separate name, they were just the later steps of glycolysis. However, when I started teaching, my students were really confused. One of my colleagues called these steps the "prep steps" and I really liked how it helped my students understand how you make acetyl coa out of pyruvate because you can't directly feed the Krebs Cycle with pyruvate. Calling it "link reaction" is actually even better, I wish I'd thought to call it that! -BOGO
@@BOGObiology Oh okay, thank you so much! My IB textbook also says that 36 net ATPs are produced at the end in a chart just like yours.. how is that? and could you explain (:
@@BreannaQuan Hi, the amount of ATP produced can fluctuate a bit for a couple of reasons. 38 is the ideal if everything is working perfectly, which it never does. The mitochondrial membrane can "leak" protons, they sneak back across the membrane without going through ATP synthase (lazy little rascals). You can see why this would be problematic at 13:00. Some cells make other membrane proteins that can transport protons through also without harnessing them to recharge ATP. Also, there are new theories that we may actually spend a little ATP hauling pyruvate around. Scientists will probably shift this figure down to the low 30s sometime in the next few years, and then all the textbooks will change and the "updated" version will cost twice as much...
In the meantime, go with whatever your textbook says (36 atp), but if asked to elaborate mention that it can fluctuate because membranes are leaky and protons are sneaky. Love, BOGO
BOGObiology Thank you sooo much 💙💙
@@BreannaQuan You're very welcome! Feel free to share and forward to classmates if you think they'd find it helpful. Sharing resources is a HUGE help when it comes to higher level science, especially in undergrad. Sending love and best wishes from Boston! -BOGO

Your video's are really helpful and deserve a lot more views, thanks! I was wondering if maybe you could do a video talking about photo respiration?
Thanks for taking the time to comment, Iris! Glad the videos are useful (I really wish this sort of tutorial had been around when I was in college). I haven't made a video specifically about photorespiration, but my video on C3, C4 and CAM plants spends a few minutes discussing it. I've linked it below. I'm 99% sure I also made a photo respiration instagram post a few months ago, but I'll have to track it down. Sending love and best wishes from Boston! -BOGO

Great video!! I just want to make sure Aerobic cellular respiration happens in the cytoplasm for prokaryotic cells, and for eukaryotic cells, it occurs in the mitochondria?
Very nice explanation,won't ever forget the kreb's cycle though😂
great work 👍👌👌😍👏👏
Thanks! So glad you liked it! Sending love from Boston -BOGO
you used the pedagogical method of dual coding so well to explain this; kudos and thanks a lot...also me at 07:43 O.o. :p
Gotta keep it interesting somehow! My students always enjoyed that example, but I had to teach it to them on the DL haha. Sending love and best wishes from Boston! -BOGO
thanks a lot for the APA citation; such a relief, phew! Also, I bought your PDFs at Etsy and will be using them to train a couple of science teachers; not commercial purposes, so hope it's okay.
Hi! Thank you so much for this informative video. I wanted know when doubling the number of molecules produced in the Krebs cycle, why does NADH go from 6 to 10. Shouldn’t it be 12 if i am doubling it and why does FADH2 stay the same (2)?
Hi! Great question. You make 3 loaded NADH per rotation of the Krebs Cycle, for a total of 6. You already made 2 NADH in Glycolysis and 2 in the Prep Steps, for a total of 10. Hope that helps! Love BOGO
This was so helpful! I was struggling with this topic. Are the 'prep steps' the same as the link reaction?
Thanks! And yes, a lot of places call the "prep steps" the linking reactions, or just lump them in with glycolysis. My students found it really helpful to separate them out, though, so that's what I've always done! Love from boston! -BOGO
Which app do you use to create the animation?
DAMN CINDY
Cindy is absolutely who your mama warned you about. She's doing the Kreb's Cycle with all kinds of different reagents ALL THE TIME.
Anerobic - Fermentation please
It's fantastic and very helpful thanks a lot
😍😍
How exactly are 6 water molecules formed in cellular respiration? Great video BTW!!
Good question! It happens in the ETC. Check out 12:20 to see it! Love, BOGO
why does the krebbs cycle only produce 1 CO2 after one cycle when it loses a CO2 from isocitrate and 1 from ketoglutarate?
Why can't I learn this freaking Kreb's cycle? HELP!
You're not alone
If ATP is generated from each H+ brought to the mitochondria matrix through ATP synthase, shouldn't that produce a lot more ATP than 1?
Depends how in depth you want to get. Here, I depicted ATP synthase as a tube because that was appropriate for the difficulty level of this video, but it's more like a water wheel. The y subunit rotates, and generates a few ATP for each complete rotation, but it requires a number of protons to rotate. However, science is notoriously sloppy, and a bunch of protons invariably sneak through the membrane when nobody is looking without passing through the synthase protein, so your yield is always a bit lower than would be ideal (it's why you get different ATP yields in different texts). Khan actually does a pretty solid video on calculating ATP yield that's more at MCAT level than this (this is roughly advanced high school to early university level, give or take). Good luck!
@@BOGObiology That makes sense. Thank you!
@@annieschulz4201 Just remember "Membranes are leaky, and protons are sneaky!" (And that chemistry is always a sloppy endeavor and NOTHING in it ever works in real life as well as it does on paper) Love, BOGO
anaerobic respiration/fermentation video plss
Great idea! I'll get to it eventually! Sending love and best wishes from Boston! -BOGO
Glycolysis also use oxygen?
Nope! No oxygen needed for glycolysis. The down side is that it only produces a few charged ATP. See 5:44 for the summary. Sending love and best wishes from Boston! -BOGO
Holly shit the pneumonic caught me off guard . I got so scared 😂😂😂😂 not used to teachers saying things like that !!!
Ha! There are a lot of semi-naughty mnemonics in science! Like the one for remembering Domain, Kingdom, Phylum, Class, Order, Family, Genus, Species. (Dumb Kids Playing Catch On Freeways Get Squished), or the "Four Fs" for the roles of the sympathetic nervous system; (fight, flight, fright and... um, reproduction ) ! ; )
In retrospect, however, I probably shouldn't have included it, even though it's so great for helping one to remember the molecules. The data from youtube analytics tells me that 90% of my viewers are in their 20s and thus should be okay with a bleeped expletive, but some people still get very, very upset by it. Maybe I'll include a massive warning label next time. Sending love from Boston! -BOGO

Thanks for the feedback; I'm working on it. I invested in a new mic but I have to record all my videos in my apartment. I don't have access to a recording studio.
George Floyd went 8 minutes and 27 seconds without oxygen
Hi Mash. I want to make sure I'm very clear; George Floyd was killed in a despicable, sadistic and racist act of murder by a group of police officers.
While it is true that about 3 minutes of sudden total oxygen deprivation will cause unconsciousness followed shortly by death, this is not precisely what happened to Mr. Floyd. Rather, the police officers gradually cut off his air supply by kneeling on his neck and torso. They continued to do so even as he gasped desperately for air, begged to be allowed to breathe, and after he ultimately lost consciousness. Mr. Floyd was slowly and horribly asphyxiated over the course of 8 minutes and 46 seconds. Gradually being strangled over such a long period of time was almost certainly excruciating both physically and emotionally for Mr. Floyd. I will personally do everything in my power to fight for reform and to help make sure that his killers are brought to justice for their despicable actions, and I hope you will, too.
If you (or anyone reading this) needs someone to talk to, please feel free to reach out. I won't pretend to have all the answers, but I can promise to listen. My email address is linked in my channel profile. Love, BOGO
BOGObiology this is so kind of you. 💗
@@BOGObiology And what happened to Tony Timpa? I know that he was white and none of the officers responsible for his asphyxiation were charged, but can you help me out on the scientific explanation of his death?
@@tpstrat14 Hi Timothy, I hadn't personally heard of Tony Timpa, thanks for bringing that to my attention. It seems like it's yet another situation in which a person in custody was asphyxiated, though the official autopsy also listed cocaine toxicity as a contributing factor. Though I'd take that with a grain of salt. Pretty amazing how the cocaine toxicity only kicked in AFTER the arrest...
I'll try to summarize how this occurs as conscientiously as possible.
Essentially, every cell in the body requires a constant supply of oxygen. 24 hours a day, 7 days a week. There are basically no exceptions to this rule. Some cells (like brain cells and cardiac cells) are especially sensitive; they can only survive a few minutes without oxygen before they start to wither and die. Cells use oxygen in a series of complicated reactions to charge energy storage molecules so cells have energy to do their thing. Brain cells use the energy to conduct impulses, cardiac cells can have energy to contract and pump blood, etc etc.
If someone is strangled, drowning, choking on a piece of food, etc, they cannot bring air into their lungs. Oxygen suddenly cannot be delivered to these crucial tissues, so cells use up all their stored energy and then suddenly need more. At about 12:15 in the video, I talk about the role of oxygen in respiration. Oxygen plays a crucial role in the electron transport chain, which creates many many units of stored energy. The cell suddenly goes from creating about 38 units per molecule of glucose to only about 2, which isn't nearly enough. Eventually, crucial bodily functions no longer have the energy to function; for instance, the diaphragm stops pulling air into the lungs, the heart muscles beat more slowly and then stop, etc. If you're "lucky" this happens very quickly. If not, you suffocate slowly and die gasping for air. Horrible.
I should add that, as an EMT, I've had to do a number of "holds" on patients who were actively harming themselves (smashing their heads on a cement floor, biting into their own wrists, ripping into their own flesh with their fingernails etc) as a result of drug use and/or mental health troubles. We use bandages or velcro cuffs for immobilizing wrists or ankles, rather than sitting on a person. I cried after my first hold, it was terrible, but the alternative was watching someone bash their own brains out on the floor, literally. HOWEVER, there are absolutely ways to restrict someone's movement in the name of safety while minimizing risk to oneself and risk to one's patient. You never, ever kneel or put body weight on a patient's neck or chest, period. In most of these instances where someone is killed, officers are sitting or kneeling on the person's neck, chest and/or back, compressing either their lungs, their carotid artery or both. The person feels the urgent drive to breathe and often involuntarily flails trying to get away. Officers often take this as a sign of "resistance", and interpret it as needing to hold the person down harder. Horrible. Horrible, horrible. Hope this helps clarify. Love, BOGO
@@BOGObiology First of all, thanks for these videos. They're very well done and are helping me a lot!
Secondly, of course you hadn't heard of Tony Timpa. He's white. And George Floyd tested positive for COVID, fentanyl and methamphetamine. Did you know that? Just curious
My only real concern with this video is the incorrect calculation of ATP from NADH and FADH2. Revised values have been calculated that put the value to 30 -32 ATP.
Hi, I think I answered this in a couple other comments but yes the *actual* value is lower because membranes are leaky and protons tend to find ways to slip through when nobody is looking. This is more like an idealized number if everything works perfectly (but, with science of course it never does...) Sending love from Boston! -BOGO
I have a question, Can cell produce glycolysis without glucose?
Nope, you need glucose for glycolysis. There's another process called gluconeogenesis that converts fat into glucose and then does glycolysis with that glucose, but that's all I'm aware of. Hope this helps! -BOGO
haha thx
There is a confusion in this video, there is no such thing as anaerobic respiration in eukaryotes. Technically speaking fermentation Is not a type of respiration as glucose is not completely oxidized to atp and water. Anaerobic respiration is when the final electron acceptor is something other than Oxygen but the electron transport chain still goes; this is not the case in fermentation.
The Kreb's Cycle is every Cindy's least favorite subject.

Hi Luke. The content is effin' hard, and you're in good company. Only about 20,000 confused students have watched this particular video, but the introductory version is up to almost a quarter million. There's a reason so many people are looking for better explanations; it's complicated. If you're still confused, it might help to start here with the intro version, then come back here. ruclips.net/video/xmfhKbmQhq0/видео.html Sending love and best wishes from Boston! -BOGO
this is a lot
i understood everything until etc...
Yeah, that's fair, the ETC is confusing. It might help to think about it "backwards" from big picture to small.
The goal of respiration is to recharge ATP.
In order to recharge ATP, you have to push a whole bunch of protons through the atp synthase protein.
To get the protons onto the correct side of the ATP synthase protein, you use proton pumps.
The pumps need power to suck the protons from one side of the membrane to the other.
NADH and FADH2 deliver the electrons that power those pumps.
The Kreb's cycle re-loads NAD and FAD so they're ready to power the pumps.
Now put it all together in the correct order: "NADH and FADH2 deliver electrons, which power the pumps, which move the protons, which turn the ATP synthase protein, which recharges ATP." Hope this helps! Love BOGO
you speak too fast huhu
Sorry! I get a lot of comments asking for me to slow down or speed up; I can never seem to make everyone happy!! Definitely try making use of the pause button, or the little gear icon to slow the video down to 75%. Hope that helps! Love, BOGO
