WebJun 8, 2024 · Figure 6.11. 1: Feedback inhibition: Metabolic pathways are a series of reactions catalyzed by multiple enzymes. Feedback inhibition, where the end product of the pathway inhibits an earlier step, is an important regulatory mechanism in cells. The production of both amino acids and nucleotides is controlled through feedback inhibition. WebNov 11, 2024 · Allosteric inhibition generally acts by switching the enzyme between two alternative states, an active form and an inactive form. It usually works by binding to a sites in a specialized subunit of a mutimeric protein, and thus binds at several sites. The more inhibitor that binds, the more then can bind, and vice versa with substrate.
