Metabolic reactions, such as anabolic and catabolic processes, must proceed according to the demands of the cell.
Web16 mei 2024 · Enzymes’ activity can be inhibited in a number of ways: Competitive inhibitors – a molecule blocks the active site so that the substrate has to compete with the inhibitor to attach to the enzyme. Non-competitive inhibitors – a molecule binds to an enzyme somewhere other than the active site and reduces how effectively it works. Web19 sep. 2024 · Phosphorylation provides another mechanism by which enzymes can be inhibited. This typically occurs through the action of kinase enzymes, which can either …
