Which Cellular Respiration Process is Absolutely Dependent Upon a Supply

Question

Which cellular respiration process is absolutely dependent upon a supply of NADH?
A) glycolysis
B) the electron transfer system
C) pyruvate oxidation
D) the citric acid cycle

Accepted Answer

The electron transfer system (also known as the electron transport chain) is absolutely dependent upon a supply of NADH because NADH donates electrons to the chain, which is crucial for the process of oxidative phosphorylation to produce ATP.
