Feedback inhibition occurs when the end product of a pathway inhibits the enzyme that catalyzes the first step of the same pathway. This helps to regulate metabolic reactions and prevent the buildup of unnecessary or harmful products. Reversible covalent modification refers to the reversible addition or removal of a chemical group to or from a protein, which can alter its activity or localization. Metabolic channeling refers to the spatial organization of enzymes within a cell or organelle, which can facilitate the efficient transfer of intermediates between different pathways. Non-competitive inhibition occurs when an inhibitor binds to a site on an enzyme that is separate from the active site, which can reduce the enzyme's activity without directly blocking substrate binding.
