Quizplus · Accepted Answer

Gluconeogenesis is the pathway that synthesizes glucose from non-carbohydrate precursors, uses 7 of the same enzymes as glycolysis, but must replace 3 enzymes of glycolysis because they are irreversible (hexokinase, phosphofructokinase, and pyruvate kinase). Glycogenolysis is the breakdown of glycogen to glucose, not the synthesis of glucose. Oxidative phosphorylation is the process by which ATP is produced from the transfer of electrons from NADH and FADH2 to oxygen through a series of electron carriers. Fatty acid synthesis is the process by which fatty acids are synthesized from acetyl-CoA. None of these pathways fit the description of synthesizing glucose from non-carbohydrate precursors and using 7 of the same enzymes as glycolysis, while replacing 3 irreversible enzymes.
