Question

Each FADH2 has enough energy to produce how many molecules of ATP?

Answer 1

In aerobic respiration, each FADH2 molecule can produce 2 molecules of ATP.

Step-by-step explanation:

ATP Yield from Aerobic Respiration of Glucose

In aerobic respiration, the electrons from one molecule of NADH generate enough energy to produce three molecules of ATP, while the electrons from one molecule of FADH₂ produce two molecules of ATP. Therefore, each FADH₂ can produce 2 ATP molecules.

The ETC, which is part of aerobic respiration, produces about three ATP for every oxidized NADH, but only about two ATP for every oxidized FADH₂. This is because FADH₂ starts at a lower point in the ETC compared to NADH, resulting in the production of fewer ATP molecules.
