How many protons are pumped across the inner membrane for each FADH₂ molecule that enters the electron transport chain?

Question

Quizplus · Accepted Answer

FADH2, when it enters the electron transport chain, results in the pumping of 6 protons across the inner mitochondrial membrane. This is because FADH2 donates electrons to the electron transport chain at a later point than NADH, specifically at complex II, thus contributing to fewer proton pumps compared to NADH, which contributes to pumping 10 protons.
