A characteristic of the glycerol phosphate shuttle is A) it shuttles NADH across the mitochondrial membrane to yield 5 ATP\NADH B) it shuttles the electrons from NADH across the mitochondrial membrane to FADH₂, yielding 5 ATP\NADH C) it only operates efficiently at high levels of NADH D) malate is a key component in the shuttle process

Question

Quizplus · Accepted Answer

The glycerol phosphate shuttle transfers electrons from NADH across the mitochondrial membrane to FAD, forming FADH2, which then enters the electron transport chain, yielding approximately 1.5 ATP per NADH, not 5 ATP as stated. This process differs from the malate-aspartate shuttle, where malate is a key component, not in the glycerol phosphate shuttle.
