Citrate–malate shuttle

WebThe metabolic shuttle cycle using malic enzyme involves the conversion of pyruvate to malate in the mitochondrion, which is then transported to the cytosol where it is converted back to pyruvate. During this process, NADH is oxidized to NAD+ in the cytosol, and NADP+ is reduced to NADPH in the mitochondrion. The net effects of this cycle are: Web1 day ago · Determiners of cell fates: the tricarboxylic acid cycle versus the citrate …
