Which of the following is a characteristic of the malate-aspartate?
A)Electrons of cytosolic NADH are translocated to mitochondrial NADH.
B)OAA is translocated to the inner mitochondrial membrane.
C)There is only one malate dehydrogenase enzyme.
D)The reactions are irreversible.

Question

Quizplus · Accepted Answer

The malate-aspartate shuttle involves the transfer of electrons from cytosolic NADH to mitochondrial NADH via the transport of malate and oxaloacetate (OAA) across the inner mitochondrial membrane. This allows for the production of ATP in the mitochondria to support cellular energy needs. The shuttle involves two enzymes, malate dehydrogenase and aspartate aminotransferase, and the reactions are reversible. Therefore, the correct characteristic is that electrons of cytosolic NADH are translocated to mitochondrial NADH.
