Carbohydrate anabolism

Carbohydrate anabolism. We have covered some aspects of carbohydrate catabolism: glycolysis, PPP, citric acid cycle, etc. and now we turn to carbohydrate anabolic pathways that utilize ATP and reducing power for biosynthesis (ATP used to make favorable reactions)

Summary of the citric acid cycle

Summary of the citric acid cycle. For each acetyl CoA which enters the cycle: (1) Two molecules of CO 2 are released (2) Coenzymes NAD + and FAD (Q) are reduced (3) One GDP (or ADP) is phosphorylated (4) The initial acceptor molecule (oxaloacetate) is reformed
