Final answer:
FADH2, NADH, and Krebs cycle enzymes are essential in driving ATP synthesis during cellular respiration.
Explanation:
FADH2 is the hydrogen-carrier molecule that can drive the synthesis of up to three molecules of ATP during cellular respiration. It plays a crucial role in transferring high-energy electrons to the electron transport chain to generate ATP.
NADH is another important hydrogen-carrier molecule that participates in electron transport and aids in ATP production during aerobic respiration.
The Krebs cycle enzymes also contribute to ATP synthesis by generating energy carrier molecules like NADH and FADH2 that feed into the electron transport chain for ATP production.
