Which of the following statements is a characteristic of the glycerophosphate shuttle?
A)It shuttles NADH across the mitochondrial membrane to yield 2.5 ATP/ADH.
B)It shuttles "NADH electron equivalents" across the mitochondrial membrane to yield 1.5 ATP/NADH.
C)It operates efficiently only when the [NADH] in the cytoplasm is higher than in the matrix.
D)The molecule malate is a key component in the shuttle process.

Quizplus · Accepted Answer

The glycerophosphate shuttle shuttles "NADH electron equivalents" across the mitochondrial membrane to yield 1.5 ATP/NADH. The other statements are not characteristic of the glycerophosphate shuttle. A is incorrect as the shuttle uses FADH2 to produce 1.5 ATP instead of NADH. C is incorrect as the shuttle operates efficiently only when the [NADH] in the cytoplasm is lower than in the matrix. D is incorrect as malate is not a key component of the glycerophosphate shuttle; it is a key component of the malate-aspartate shuttle.
