Biology
In the absence of oxygen, the conversion of pyruvate to acetyl CoA, the Krebs cycle, and oxidative phosphorylation are prevented as oxygen is not available as the final electron acceptor.
Hence, only glycolysis can occur, generating 2 molecules of ATP by substrate level phosphorylation by breaking down glucose into pyruvate. Glycolysis can occur even in the absence of oxygen as the oxidising agent of glycolysis is NAD, not oxygen. A sufficient supply of NAD is available as the NAD reduced during glycolysis is regenerated by transferring electrons from NADH to pyruvate during the fermentation process.
- Krebs Cycle Broken Down
The Krebs cycle, also known as the Citric Acid cycle, is a very important process in cellular respiration. Without this portion, respiration would not be possible. This is because the Krebs cycle uses the pyruvate molecules from glycolysis to produce...
- Respiration
Respiration is the breakdown of large glucose molecules into simple molecules such as carbon dioxide and water with the simultaneous release of energy inside living cells. It is an enzyme mediated process. Main processes: Glycolysis (glucose to pyruvate,...
- Q: Describe The Role Of Nad In Aerobic Respiration
NAD is a coenzyme and an electron carrier, it acts as an electron acceptor in glycolysis and Krebs cycle through dehydrogenation processes and is then reduced to NADH. WHen it is reduced to NADH, it is utilized as an electron donor during oxidative phosphorylation....
