Question

question
which of the following is true of nadh and fadh₂?
answer
only fadh₂ can become oxidised.
nadh has more potential energy than fadh₂.
only nadh donates electrons to the electron transport chain.
only nadh is produced in the citric acid cycle.
i dont know yet

Explanation:

• Both NADH and FADH₂ can be oxidized and donate electrons to the electron transport chain.
• Both NADH and FADH₂ are produced in the citric acid cycle.
• NADH has a higher potential energy than FADH₂ because when NADH donates electrons to the electron transport chain, more protons are pumped across the inner mitochondrial membrane, leading to the production of more ATP (about 2.5 ATP per NADH) compared to FADH₂ (about 1.5 ATP per FADH₂).

Answer:

NADH has more potential energy than FADH₂.
