Enzyme reaction mechanism

WebThe mechanism of enzymatic action. An enzyme attracts substrates to its active site, catalyzes the chemical reaction by which products are formed, and then allows the products to dissociate (separate from the enzyme … WebEnzyme activity may be turned "up" or "down" by activator and inhibitor molecules that bind specifically to the enzyme. Cofactors. Many enzymes are only active when bound to non-protein helper molecules known as cofactors. Compartmentalization.
