Which of the following is not true about enzymes? 4. Transition state stabilization can significantly increase the activation energy for a reaction. Nucleophilic groups can catalyze reactions through the transient formation of covalent bonds with the substrate. Zymogens are the inactive precursors of enzyme. Enzymes typically act under milder conditions of temperature and pH than non-enzyme chemical catalysts. Enzyme inhibitors interact reversibly or irreversibly with an enzyme to alter its Km and /or Vmax values.
