Which of the following correctly describes the malate-aspartate shuttle?
1
It generates FADH2 during the transport of reducing equivalents across the mitochondrial membrane.
2
It operates primarily in skeletal muscle and brain tissue.
3
It transports reducing equivalents from the cytosol to the mitochondrial matrix by converting oxaloacetate to malate.
4
It generates NADH when oxaloacetate is converted back to malate in the cytosol.
