Malate-Aspartate Shuttle

The video explains the malate aspartate shuttle, a crucial mechanism for transporting NADH from glycolysis into the mitochondria for ATP production. It details the impermeability of the mitochondrial membrane to NADH and the role of antiporters in the shuttle process. The video covers the enzymatic reactions involved, including the conversion of oxaloacetate to malate and back, and the role of concentration gradients. It also discusses the cycle of aspartate and glutamate and the shuttle's application in gluconeogenesis.
