Question

Which important biochemical process receives a supply of NAD+ ions from the fermentation process during anaerobic respiration?

A.Calvin cycle
B.Electron transport system
C.Glycolysis
D.Krebs cycle
E. Proton pump mechanism

Answer 1

The biochemical process that receives a steady supply of NAD+ ions from the fermentation process when Oxygen does not act as the final electron acceptor would be C. Glycolysis.

Answer 2

Answer;

C. Glycolysis

Explanation;

• Glycolysis is the process by which glucose is broken down to two pyruvat6e molecules. It is the first phase of cellular respiration and occurs in both aerobic respiration and anaerobic respiration.
• However, during anerobic respiration or fermentation, pyruvate molecules from glycolysis are not converted to acetyl CoA but they are converted to lactate by lactate dehydrogenase.
• During the reduction of pyruvate to lactate NAD+ is regenerated from NADH of glycolysis, this NAD+ is taken back to drive more glycolysis and produce more energy for the cells.
