WebPlants and bacteria can convert acetyl-CoA to glucose via the glyoxylate cycle. It is a modified version of the TCA cycle; an extra malate is produced which can be converted to glucose. Since animals lack this cycle, they cannot use acetyl-CoA to make glucose because it would stop the TCA cycle. Starch/Glycogen Synthesis WebAcetyl-CoA activates pyruvate carboxylase, which converts pyruvate to oxaloacetate (OAA) for use in the gluconeogenic pathway. • Inhibition of pyruvate dehydrogenase by acetyl-CoA also increases shunting of pyruvate toward oxaloacetate. • Citrate allosterically inhibits phosphofructokinase 1, preventing a futile cycle with F1,6-BP. • csm.edu
