Enzyme activity can be regulated through various mechanisms to ensure metabolic pathways operate efficiently:
Allosteric Regulation: Involves the binding of regulatory molecules at sites other than the active site, causing conformational changes that affect enzyme activity. Covalent Modification: Involves the addition or removal of chemical groups (e.g., phosphorylation) that alter enzyme activity. Feedback Inhibition: End products of a metabolic pathway inhibit an enzyme involved earlier in the pathway, preventing the overproduction of the product.
