6.4: Gluconeogenesis - Biology LibreTexts

WebTransition of acetyl CoA to pyruvate is an irreversible reaction. So acetyl CoA cannot make glucose. The process through which glucose is synthesized from non-carbohydrate sources is called gluconeogenesis. Acetyl CoA can be converted into fatty acids. But fatty acids and ketogenic amino acids cannot be used to synthesize glucose. WebThus fatty acid oxidation elevates ATP concentrations and the concentration of both acetyl-CoA and citrate. ATP, acetyl-CoA, and citrate are important effectors during gluconeogenesis: • Acetyl-CoA activates pyruvate carboxylase, which converts pyruvate to oxaloacetate (OAA) for use in the gluconeogenic pathway. • Inhibition of pyruvate ...
