Enzymes

2. the minimum quantity of energy which the reacting species must possess in order to undergo a specified reaction.
4. the pH resulting in maximal activity of a particular enzyme.
5. process modifying the molecular structure of a protein.
8. surface or material from which an organism grows or obtains its nourishment.
11. disruption of a chemical pathway due to one chemical inhibiting the effect of another by competing with it for binding or bonding.
14. increases the frequency with which the enzyme and substrate collide.
15. assumes that the active site of the enzyme and the substrate are equal shaped.

1. a molecule that binds to an enzyme and decreases its activity.
3. type of inhibition that reduces the peak rate of a chemical reaction without changing the apparent binding affinity of the catalyst for the substrate.
6. will speed up the reaction.
7. class of macromolecules that perform a diverse range of functions for the cell.
9. a region on the surface of an enzyme whose shape permits binding only of a specific molecular substrate that then undergoes catalysis.
10. organic molecules that act as catalysts for chemical reactions.
12. the temperature at which an enzyme shows its highest activity.
13. a model for enzyme-substrate interaction.
