What is the Role of NADH in Metabolism

Question

What is the role of NADH in metabolism?
A) convert pyruvic acid into acetyl-coA
B) produce bicarbonate ions for a pH buffer
C) transport hydrogen atoms to coenzymes
D) produce carbon dioxide
E) phosphorylate ADP into ATP

Accepted Answer

NADH plays a crucial role in metabolism by transporting hydrogen atoms to coenzymes. It is a coenzyme that is involved in many metabolic pathways, including glycolysis, the Krebs cycle, and oxidative phosphorylation. During these pathways, NADH is oxidized, and its stored energy is used to produce ATP. The transportation of hydrogen atoms is essential to these energy-producing pathways.
