Question

Which answer option listed below accurately describes the fate of the cytoplasmic NADH generated by glycolysis under anaerobic conditions?

Question 12 options:

it leaves the cell, is transported by the blood to the liver, and there it serves as a substrate for the production of glucose by gluconeogenesis

it enters the mitochondria, is converted to acetyl coA and drives a revolution of Kreb's cycle for every molecule of acetyl CoA that feeds into the cycle

it undergoes intracellular digestion within a lysosome

it is re-oxidized back to NAD+ as it generates lactate by passing its hydrogen atoms to pyruvate; once re-oxidized, it can drive another round of glycolysis

Explanation / Answer

Fate of cytoplasmic NADH generated by glycolysis under anaerobic conditions (D) it is re-oxidized back to NAD+ as it generates lactate by passing its hydrogen atoms to pyruvate; once re-oxidized, it can drive another round of glycolysis.
