Vocab Quiz

3. The science concerned with the relationship between mechanical and thermal energy
5. A phenomenon displayed by enzymes or receptors that have multiple binding sites. Binding of one ligand alters the affinity of the other site.
6. The energy that exists in a body as a result of its position or condition rather than of its motion.
11. A molecule reduces the activity of the enzyme and binds equally well to the enzyme whether or not it has already bound the substrate
16. All chemical and physical processes in an organism
17. An organic or inorganic substance required for the function of an enzyme
18. A nonprotein substance that usually contains a vitamin or mineral and combines with a specific protein, to form an active enzyme system.
19. the portion of total energy of a natural system that can be used for work.

1. When one reaction is fueled by the energy from a previous reaction
2. 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.
4. that part of the energy in a substance that can be released by a chemical reaction
7. A chemical reaction where the change in the Gibbs free energy is negative,[1] indicating a spontaneous reaction.
8. The major energy source for all bodily functions.
9. A blocking of activity due to the production of an end product of the action.
10. 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
12. binding of a molecule to the active site on the enzyme prevents binding of the substrate
13. series of chemical reactions occurring within a cell
14. A chemical reaction in which the standard change in free energy is positive, and energy is absorbed.
15. the part of the total internal energy of a thermodynamic system or sample of matter that results in the system temperature.
