Anabolic pathways. so you cannot enter krebs cycle. As it takes part both in anabolism and catabolism, it is said to be amphibolic pathway of metabolism. match the cofactor with the vitamin involved: hormonal control of: cholesterol synthesis, hormonal control of: ketogenesis (making of Ketones for energy), glucagon (insulin suppresses Ketogenesis), hormonal control of: amino acid synthesis, hormonal control of: fatty acid synthesis, hormonal control of: nucleotide synthesis, hormonal control of: amino acid catabolism. Why are catabolic pathways described as convergent whereas anabolic pathways are described as divergent? (3) Amphibolic pathways, which occur at the "crossroads" of metabolism, acting as links between the anabolic and catabolic pathways, for example, the citric acid cycle. Catabolic pathways release energy while breaking down molecules into simpler molecules. Name three basic catabolic pathways, and give an estimate of how much ATP each of them yields. _________ inhibition of an enzyme occurs when the inhibitor mimics the substrate and occupies the active site of the enzyme, whereas ___________ inhibition occurs when an inhibitor binds to a regulatory site on the enzyme that is separate and distinct from the active site.
