  1. 3. inhibition a method of metabolic control in which the end product of a metabolic pathway acts as an inhibitor of an enzyme within that pathway
  2. 6. the binding of a regulatory molecule to a protein at one site that affects the function of the protein at a different site
  3. 7. the reactant on which an enzyme works
  4. 9. a process by which a chemical agent called a catalyst selectively increases the rate of a reaction without being consumed by the reaction
Down
  1. 1. the specific region of an enzyme that binds the substrate and that forms the pocket in which catalysis occurs
  2. 2. a kind of allosteric regulation whereby a shape change in one subunit of a protein caused by substrate binding is transmitted to all the other subunits, facilitating binding of additional substrate molecules to those subunits
  3. 4. a macromolecule serving as a catalyst, a chemical agent that increases the rate of a reaction without being consumed by the reaction
  4. 5. a chemical agent that selectively increases the rate of a reaction without being consumed by the reaction
  5. 6. the amount of energy that reactants must absorb before a chemical reaction will start; also called free energy of activation
  6. 8. a temporary complex formed when an enzyme binds to its substrate molecule(s)
