Web8 sep. 2024 · Malate can be oxidized into either OAA or pyruvate. OAA accumulation leads to the inhibition of the malate-oxidizing malate dehydrogenase reaction. The availability of acetyl-CoA for condensation with OAA by citrate synthase is another factor for the regulation of mitochondria malate oxidation. WebThe oxaloacetate formed in the mitochondria is converted to either malate or aspartate to enter the cytoplasm via the malate/aspartate shuttle. Once in the cytoplasm the malate or aspartate is converted back into oxaloacetate (circle 3), and phosphoenolpyruvate carboxykinase will convert it to PEP (circle 4).
