I think you saved my life! I've watched your 4 videos going through the steps of cellular respiration. I was a little hesitant because of the length (one was almost 30 minutes) but it was WELL worth my time. I feel much more confident in my understanding of this craziness now. Thanks!
In regards to the total ATP, most books and studies are using 2.5 for NADH and 1.5 for FADH2 for ATP produced. 32 ATP is what you get from 1 glucose molecule that has gone through glycolysis and the TCA. There is an argument in regards to the shuttle system that the NADH's from Glycolysis use to enter the membrane into the mitochondria. Depending on that, some believe it can 1.5 or 2.5 ATP worth based on the shuttle for those 2 in particular. So at the end of it all, you are getting 30 - 32 ATP based on what shuttle the NADH's from glycolysis used to enter the mitochondria.
Good video, though I would have liked to see more of the exact stoichiometry during ETC proton pumping(saying each complex involved in pumping pumps 1 proton is a bit misleading). Thanks for the disclaimer at the end about the ATP equivalence of the reduced cofactors(NADH/FADH2); my book/instructor is using 2.5ATP/NADH and 1.5ATP/FADH2, which would give 32 ATP/glucose per complete cycle. Overall, very clear explanation of what the ETC accomplishes!
can you help fill in the blank? As the electrons are transferred through the ETC (electron transport carrier) from NADH and FADH2 to oxygen, hydrogen ions (H+) are pumped from______ to _____of the mitochondrion

All the processes are crystal clear now. I know you hear this all the time but I will say it again! You saved my life! Thank you!
Thank you man! I wish my professor was as clear as you are. You have a great way of explaining things. Lifesaver for sure!
Finally it's clear to understand! Thank you! Among all the videos of watch, this one did it for me.

You sir are an amazing teacher! Thank you so much for making this topic so clear!
Great instruction, and very helpful. Thanks for posting these!
Great job. quit simple and illustrative. thanks

Thanks for the feedback / recommendation! I'll get working on a vid with that and hopefully put it out soon.
It's realistically 30 ATP per one glucose molecule as yields are: NADH = 2.5 ATP and FAHD2 = 1.5 ATP
you made it so easy and understandable !!! I love you , God bless!!!!
This really helped a lot!!
This was incredibly helpful, thank you so much!
thank you. this video was very informative and helpful.
saved me!
thanks, only needed expansion on how atp is formed via ATP synthase.
Thank you. Short version is good. Do you have lectures for vitamins and mineral metabolism?
I was kind of confused on how you got 10 NADH (at the end of the video when adding everything together) but I got it! haha
Thank you so much!
please make a video on carbohydrate metabolism and enzymes with clinical correlations!..thank you
Many thanks!
Greaaaaaaat job!
This is great, thank you! :)
I have a test tomorrow about that can you please tell me the functions of protein co
can you help fill in the blank? As the electrons are transferred
through the ETC (electron transport carrier) from NADH and FADH2 to
oxygen, hydrogen ions (H+) are pumped from______ to _____of the
mitochondrion
+Na dia from mitochondrial matriks to inter-membrane space. not shure if it's correct names cuz i learn in Polish
Thank you! :)
Thank you!!!!!
what does IOU stand for?
thank u
oxidative phosphorylation generates 34 atp not 38
ilove it
he's a smart hottie, win win
totally agree with you! hahaa
super cute and smart, yeeessss!
helpful
I was focusing on the video til you made a teleportation from right to left.
what is GTP???
guanosine-5-triphosphate
