I graduate with my bachelor's in biology in 2 months and this is the bane of my existence! Although I've never really understood it until your videos! Thanks Bio Jesus!
You're the best prof! I like how you even include an easy chart at the end to have all of the individual reactions in order with their respective enzymes. Wish me luck on my biochem exam 😭
Omg you literally saved me. I’m a pharmacy student and I was crying because I couldn’t understand a thing in biochemistry. Thank you so much for this video.
Minor correction, as it might cause confusion for some viewers -- alpha-ketoglutarate was mispronounced as "alpha-ketoglutaMate" (the "R" was erroneously replaced with an "M" when you were speaking). The text on the screen was correct, but the pronunciation was off. Just wanted to point that out in case anyone got a little confused.
I was given this topic to report by my teacher and was really confused, out of all the videos I watched this one was the easiest to understand, thank you prof❤️
hey man photosynthesis is what welcomes us into biology. It will give us a nice hug, and as we tell it how easy it is, its friends glycolysis and krebs cycle will come and stab us from behind, then drag our dead body along with the thousands of other students murdered by them. but the professor dave is the one who stops them in the nick of time, with is unbreakable shield this is getting cringey ill stop
@@msadjei9147 Kelvin's cycle and light dependant reactions? It's still easier than glycoloysis and kreb's cycle and all that stuff, there's also a third stage in cellular respiration, this is harder the photosynthesis
@@msadjei9147as he said he's just a kid in highschool so even if they have done light and dark reactions that won't be of much detailed way (in short: don't give him trauma 💀💀let him be contented by the thought that photosynthesis is easier🙂🙂)
During aerobic respiration, formation of 2 molecules of metabolic water is coupled with formation of 6 ATP molecules for the process. (a) Tricarboxylic acid cycle (b) Oxidation decarboxylation (c) Fermentation (d) Pentose phosphate pathway (Stuck in this question, needed help)
Wow! The Krebs cycle looks scary at first, but you "break it down" (get it?) and cause it to present a much less daunting task. I have one question though. The Krebs Cycle is an aerobic process, but I didn't see any mention of oxygen in this video. When is O2 used, and where?
EpicSelenium34- Oxygen is consumed at the end of the electron transport chain during oxidative phosphorylation, when those electrons are passed to oxygen and H+ to form water. Oxygen is therefore referred to as the "terminal electron acceptor".
@@ProfessorDaveExplains Well, in 3:29 on the (2) Cellular Respiration Part 1: Glycolysis video you state that glycolysis is anaerobic, no O2 needed process.
@@ProfessorDaveExplains Thank you very much! I appreciate your reply and your videos! I really like that you go from the basics to more advanced information, like in the Glycolysis video, you first showed the basic scheme of what happens in that process and that there are 10 enzymes involved and then talked about the enzymes. THANK YOU for your biology videos!
I feel your pain my friend. Got a biochem resit tomorrow and this stuff is going in one ear and out the other. Unfortunately I have to deal with this nonsense in order to eventually look down microscopes for a living.
big thanks :D, and heres a note. * I summed up all the CO2 from the three phases and got 4 CO2 (? uh, supposedly 6 CO2 in the Equation for Aerobic Respiration) 1 Glucose + 6 O2 → 6 CO2 + 6 H2O + Energy * for the sake of fixing this problem... I've found out something hidden: Transferring 1 Pyruvate to CoA gives 1 CO2 Molecule. * thus for 1 glucose = 2 Pyruvate, Krebs gives 4 CO2 (from main cycle) + 2*1 CO2 (from transfer to CoA) so 6 CO2.
Why does when there is more concentration of ATP the citric acid cycle has a slower rate and when there is a low concentration of ATP, it has a faster rate?
I know this is late, but it's due to regulation in glycolysis. When there is a high [ATP], both phosphofructokinase (Fructose 6-Phosphate -> Fructose 1,6-BP) and Pyruvate Kinase (phosphoenolpyruvate -> Pyruvate) are allosterically inhibited by ATP. When there's high ATP, glycolysis is inhibited, and gluconeogenesis is promoted to form glucose. This usually happens in a fasted state
funny how these videos are already extremely condensed and shortened and i'm just gonna be taking 3 of them and condensing them even further into a 5 or 6 min video.
So do you think the supplement Arginine alpha-ketoglutarate is healthy to take for increasing nitric oxide for people with high blood pressure and athletes? Or is it dangerous to overload the kreb cycle with alpha-ketoglutarate?
Plants did not evolve before aerobic respiration. The first organisms that flooded the world with oxygen were single cellular cyanobacteria, which lead to the Cambrian explosion. Plants evolved much later.
lol mate you're a legend, you managed to explain one lecture's worth of content in 5 minutes!!! Genius.

Can someone tell me why it's called alpha ketoglutarate?
You make biochemistry much easier , thank you 🌹
Thank you for the subtitles! Helps a lot foreigners :)
Thank you so much Prof. Dave, you give me hope that I might pass my exam

I am just a kid in highschool trying to understand this. I just wanted to say photosynthesis is easier than cellular respiration.
hey man
photosynthesis is what welcomes us into biology. It will give us a nice hug, and as we tell it how easy it is, its friends glycolysis and krebs cycle will come and stab us from behind, then drag our dead body along with the thousands of other students murdered by them.

Have you done the light and dark stages of photosynthesis

God damn I'm a physics student, never realised that so many reactions are taking place. Mind boggling.
Thank you for sharing your knowledge and for the taking the time to create these graphics!
i like the color coding to separate different reactions.
These are so helpful for biology, thank you

That's in glycolysis! Check out Part 1, the clip right before this one.

Ooh yeah, I'm not sure what I meant by that super old comment. Molecular oxygen is the final electron acceptor in the electron transport chain.

The number of ATP produced when a molecule of acetyl coenzyme-A is oxidized through citric acid cycle is??????

D-15

very late reply but nice
I still dont understand this part of cellular respiration. Glycolysis is easy enough but this is just awful
Thank you processed
You are a lifesaver!!
Very beautifully illustrated
Thank you
you're awesome thank you so much for these videos
Is this guy a teaching genius or what?
the acetyl CoA comes from the pyruvate oxidation,what about the oxaloacetate, where does it come from 💔?
I think it's just a constant
I call this guy “Biolo-Jesus”
3:38 is the summary
i understand the cycle but why does this depend on resparation, where does the ogygen have an influence ?
IM A GRADE 9 AND IM HERE TRYING TO UNDERSTAND THE CELLULAR RESPIRATION BECAUSE OF MY EXAM FOR TOMMOROW, I HOPE THAT I WILL PASS THAT DJWANDJAWN EXAM
Endosymbiotic theory proposes that mitochondria were once a separate organism

it's all in there
So do you think the supplement Arginine alpha-ketoglutarate is healthy to take for increasing nitric oxide for people with high blood pressure and athletes? Or is it dangerous to overload the kreb cycle with alpha-ketoglutarate?
