Question

Among the products of glycolysis, which compounds contain energy that can be used by other biological reactions?a) ATP onlyb) pyruvate, ATP, and NADHc)CO2 onlyd) O2 onlye) pyruvate and ATP onlyf) NADH onlyg) ATP and NADH only

Answer 1

Answer: A (ATP only)

Explanation:

Both NADH and pyruvate are energy store. NADH and pyruvate can not directly be used to drive biological reaction.The metabolism of pyruvate releases energy in the form of ATP. NADH produces ATP through the electron transport chain (ETC). Adenosine Triphosphate (ATP) is referred to as the energy currency of the cell. ATP is used directly as energy to drive endergonic and exergonic biological reaction.

Answer is ATP only
