What shuttle mechanism transfers cytosolic NADH into the mitochondria with a loss of reductive power, with the electrons entering the electron transport chain as ubiquinol instead of NADH?

Question

Quizplus · Accepted Answer

The glycerol-3-phosphate shuttle transfers cytosolic NADH into the mitochondria, resulting in a loss of reductive power because the electrons enter the electron transport chain as ubiquinol (QH2), which is at a lower energy level than if they were transferred directly as NADH.
