Citrate–malate shuttle

The malate-aspartate shuttle (sometimes simply the malate shuttle) is a biochemical system for translocating electrons produced during glycolysis across the semipermeable inner membrane of the mitochondrion for oxidative phosphorylation in eukaryotes. These electrons enter the electron transport chain of the mitochondria via reduction equivalents to generate ATP. The shuttle syst… Web1 day ago · Determiners of cell fates: the tricarboxylic acid cycle versus the citrate …
