5. When one reaction is fueled by the energy from a previous reaction
8. A nonprotein substance that usually contains a vitamin or mineral and combines with a specific protein, to form an active enzyme system.
9. A chemical reaction where the change in the Gibbs free energy is negative,[1] indicating a spontaneous reaction.
10. A chemical reaction in which the standard change in free energy is positive, and energy is absorbed.
11. A blocking of activity due to the production of an end product of the action.
12. 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
13. A phenomenon displayed by enzymes or receptors that have multiple binding sites. Binding of one ligand alters the affinity of the other site.
14. binding of a molecule to the active site on the enzyme prevents binding of the substrate
18. 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.

1. that part of the energy in a substance that can be released by a chemical reaction
2. The science concerned with the relationship between mechanical and thermal energy
3. the part of the total internal energy of a thermodynamic system or sample of matter that results in the system temperature.
4. series of chemical reactions occurring within a cell
6. A molecule reduces the activity of the enzyme and binds equally well to the enzyme whether or not it has already bound the substrate
7. The energy that exists in a body as a result of its position or condition rather than of its motion.
14. An organic or inorganic substance required for the function of an enzyme
15. All chemical and physical processes in an organism
16. the portion of total energy of a natural system that can be used for work.
