WOW! I feel like a boss right now. This material can be overwhelming, yet this breakdown has allowed me to see the light. You have shown me the way like David Goggins has. I wish you exponential success!! I appreciate you!!
Nice video overall, but there’s a mistake. When pyruvate is decarboxylated into acetylCoA, there is no O2 coming in to bind to C and form CO2. The CO2, i.e. COO, is simply the carboxylic function (COOH) that came from the pyruvate. However you didn’t mention the CoA that comes in at that step to form acetylCoA. O2 only comes into play at the end of the electron transport chain.
This is by far the most efficient and simple explanation I've seen on bioenergetics related to the NASM program. Thank you so much, I'm currently cramming for my exam in one month!
I am gonna take CSCS exam next month, i must tell you i was having a hard time getting clarity about glycolysis but your explanation nailed it ! Thank you for sharing it. God bless you bro 👍
Man, Im doing my PT cert right now and wow.. thank you so much for being able to lay all this out. The text I have is really hard to digest compared to your explanation. Really man, thanks.
im a little bit confused. you said that glycolysis doesn't need oxygen. but you wrote above the diagram "aerobic glycolysis" and said that if you didn't have oxygen, you would get lactate.
Yes. The process of glycolysis is occurring in the cytoplasm without oxygen. It's what happens after glycolysis that determines if it's aerobic or anaerobic. So if after glycolysis is done there is room in the mitochondria for the pyruvate to be metabolized the process is considered aerobic glycolysis and the pyruvate moves onto the Krebs cycle. If there is not oxygen in the mitochondria then the pyruvate will turn into lactate. That is termed anaerobic glycolysis. The terminology is confusing because in both cases the process of glycolysis didn't require oxygen.
Do questions on something like this require absolute recall of all these molecules and complete process or just being familiar with it at a higher level?
form 4:30 onwards i just became completely lost. I dont understand the NADH bit and how it correlates to the krebs cycle. And the atp part, 2 extras form glycolysis amd the timsing by 3 to make 30 atp doesnt make sense to me either. Can someone recommems a video to help break this part down. tyy :)
I'm confused. My textbook says that a net yield of 32 ATP is given "from energy transfer during the complete oxidation of one glucose molecule in glycolysis, the citric acid cycle, and electron transport." What am I missing here?
Hey Matt! Are you a wizard? Just watched your vids lately and I was thinking to myself "maybe you should ask him to make a bioenergetics vid". lol thank you so much! :)
did you mean to say anaerobic glycolysis instead of aerobic glycolysis (because you said the aerobic glycolysis doesn't need O2 but the definition of aerobic says it requires O2 and anaerobic doesn't require O2???
Neither require oxygen actually. These are both done in the cytoplasm without oxygen. Aerobic glycolysis just indicates that once split, the pyruvate will continue on to the mitochondria and use oxygen to break down more in the Krebs cycle. Anaerobic indicates that the pyruvate will turn into lactate.
Hey man, just want you to know THIS WAS A GOOD VIDEO Probably can always get better but this was very good and I’m here totally randomly and a huge critic lol In case it helps to know; I Randomly found this searching up “bio energy” which is some jokey new age health nut shit I watched “Philion” make fun of
