Answer: The answer is B
[Glycolysis]--> [pyruvic acid ->acetyl CoA] --> [citric acid cycle] --> [electron transport chain].
Explanation:
During cellular respiration, one molecule of glucose is broken down into two molecules of pyruvic acid (pyruvate) in a series ten enzyme-catalyzed reaction known as glycolysis. The pyruvic acid is further converted to Acetyl CoA which enters the citric acid cycle where it combines with oxaloacete in a series of reactions to produce GTP, NADH and FADH2. NADH and FADH2 then enters the electron transport chain where they are oxidized to produce ATP.
