Document Summary
Some conditions favor biosynthesis , where others favor catabolism. Glycolysis : a stage 2 pathway for the degradation of carbohydrates in both aerobic and anaerobic cells. Glycolysis leads to the 3 - carbon intermediate pyruvate, coupled to the production of a small amount of atp. * in aerobic organisms, all catabolic pathways converge at the citric acid cycle. When oxygen is present, pyruvate undergoes oxidative metabolism (cid:8869) pyruvate is oxidized to acetyl - coa. The 2 carbons in the acetyl group undergo oxidation in citric acid cycle. Citric acid cycle accepts acetyl-coa derived from and completes carbohydrates , lipids, the oxidation of these feels to co2 or proteins, Oxidative reactions of the citric acid cycle generate reduced electron carriers that are then reoxidized to drive the synthesis of atp (cid:8869) occurs through electron transport and oxidative phosphorylation. Gluconeogenesis : synthesis of glucose from noncarbohydrate precursors.
