How enzymes decrease activation energy
Web17 dec. 2024 · How do enzymes decrease activation energy? Enzymes decreases activation energy by shaping its active site such that it fits the transition state even better than the substrate. When the substrate binds, the enzyme may stretch or distort a key bond and weaken it so that less activation energy is needed to break the bond at the start of … Web4 mrt. 2024 · In some cases, enzymes lower the activation energy by directly participating in the chemical reaction. For example, certain enzymes that hydrolyze ATP form a covalent bond between phosphate and amino acid in the enzyme that may have a charge that affects the chemistry of the reactants.
