WebJul 17, 2024 · An enzyme activator is a molecule that positively regulates an enzyme's activity. Many enzymes require activators to begin or continue a process, recognize a substrate, or reach their maximum ... WebThe most common method by which cells regulate the enzymes in metabolic pathways is through feedback inhibition. During feedback inhibition, the products of a metabolic pathway serve as inhibitors (usually allosteric) of one or more of the enzymes (usually the first committed enzyme of the pathway) involved in the pathway that produces them.
