Question

More free energy is released during the citric acid cycle than during glycolisis, but only 1 mole of ATP is produced for each mole of acetyl-CoA that enter the cycle. Wht happens to the remaining free energy that us produced during the citric acid cycle?

Answer 1

Cellular respiration consists of 3 sequential metabolic processes: glycolysis, Krebs Cycle, and the electron transport chain.

Although Kreb's cycle doesn't directly produces ATP, it does produces NADH and FADH2, which are then oxidized by the electron transport chain to create ATP, because they can be used to reduce other molecules, which means B is the correct answer.
