  1. 3. Proteins that help speed up chemical reactions in out cells. They act as catalysts.
  2. 4. The specific molecule that an enzyme acts upon during a chemical reaction.
  3. 5. When the active site undergoes a slight change in shape to accommodate and bind to the substrate more snugly as the substrate approaches.
  4. 6. Molecules that can bind to the active site of an enzyme and compete with the substrate for binding.
  5. 8. The minimum amount of energy required for a chemical reaction to occur.

  1. 1. Molecules that can bind to an enzyme at a site other than the active site.
  2. 2. A regulatory mechanism that helps regulate enzyme activity and prevent the overproduction of certain molecules.
  3. 7. Non-protein molecules that help enzymes carry out their functions effectively.
  4. 9. Small organic molecules that assist enzymes in carrying out their functions. They often bind to the active site of an enzyme and participate in the chemical reactions.
  5. 10. A specific region on an enzyme where a substrate binds and undergoes a chemical reaction.
