Question: The action of malic enzyme opposes the action of pyruvate carboxylase. (a) Diagram the substrate cycle formed by these enzymes plus a third enzyme. (b) Write the net equation for converting malate to pyruvate and back to malate. What does this accomplish for the cell?
Malate generated inside the mitochondrion is translocated to the cytosol, where it is a substrate for cytosolic malic enzyme, which catalyzes the following reaction:
Explain how the activity of malic enzyme, which appears to catalyze a catabolic process, can promote biosynthetic reactions in the cytosol.
