2. A nonprotein substance that usually contains a vitamin or mineral and combines with a specific protein, to form an active enzyme system.
5. An organic or inorganic substance required for the function of an enzyme
6. All chemical and physical processes in an organism
7. series of chemical reactions occurring within a cell
8. binding of a molecule to the active site on the enzyme prevents binding of the substrate
10. The energy that exists in a body as a result of its position or condition rather than of its motion.
13. A chemical reaction in which the standard change in free energy is positive, and energy is absorbed.
15. The energy possessed by a body because of its motion, equal to one half the mass of the body times the square of its speed
18. When one reaction is fueled by the energy from a previous reaction
19. The science concerned with the relationship between mechanical and thermal energy

1. involving a change in the shape and activity of an enzyme that results from molecular binding with a regulatory substance at a site other than the enzymatically active one.
3. A phenomenon displayed by enzymes or receptors that have multiple binding sites. Binding of one ligand alters the affinity of the other site.
4. A molecule reduces the activity of the enzyme and binds equally well to the enzyme whether or not it has already bound the substrate
9. A chemical reaction where the change in the Gibbs free energy is negative,[1] indicating a spontaneous reaction.
11. A blocking of activity due to the production of an end product of the action.
12. that part of the energy in a substance that can be released by a chemical reaction
14. the portion of total energy of a natural system that can be used for work.
16. the part of the total internal energy of a thermodynamic system or sample of matter that results in the system temperature.
17. The major energy source for all bodily functions.
