Ch. 5 AP Biology

2. This is the energy of motion.
4. Cell "taking a drink" of extracellular fluid.
10. The specific amount of energy required to get a chemical reaction started.
11. This is a measure of disorder or how dispersed energy is
12. Small metal ions or molecules that assist enzymes
14. Situation where solute concentrations are the same on both sides of a membrane
16. Chemicals in foods that limit oxidation by free radicals.
17. The acceleration of a chemical reaction by a molecule that is unchanged by the reaction.
20. A type of regulation where a molecule binds to an enzyme somewhere other than the reaction site.
22. The capacity to do work.

1. A disease where the liver becomes hardened, scarred, and filled with fat.
3. A reaction that will not proceed without energy input.
4. A reaction that transfers a phosphate group
5. Type of transport that requires energy expenditure.
6. Term for a specific molecule that fits the active site of an enzyme.
7. Cell eating another cell
8. In living and mechanical things, energy is generally wasted in this form.
9. Chemical bonds have this type of energy.
13. Type of diffusion that uses a transport protein but no free energy.
15. An element that loses electrons becomes
18. This type of inhibition occurs when the product of a reaction inhibits other enzymes in the series.
19. The random spreading of molecules without energy input.
21. The pressure that water exerts against a cell wall in plants.
