Question

aerobic cellular respiration may produce a total of how many molecules of atp from one glucose molecule?
a 38
b 2
c 34

Explanation:

Step1: Recall aerobic respiration process

Aerobic cellular respiration has glycolysis, Krebs cycle and electron - transport chain.

Step2: Calculate ATP production

Glycolysis produces 2 ATP directly and some NADH which can produce more ATP in the electron - transport chain. The Krebs cycle also produces ATP, NADH and FADH₂. Through the electron - transport chain, the total ATP production from one glucose molecule is about 38.

Answer:

A. 38
