Biology

4. All of the chemical processes that build up or break down materials.
7. Precipitation that isn't absorbed into the soil which moves from the ground surface into places that water collect.
9. A lipid that has a ring structure.
11. Fat-soluble, plays a key role in helping the blood clot prevent excessive bleeding.
13. It prevents the natural substrate from binding to the enzyme.
14. A theory that states all living organisms are composed of cells.
15. A site that allows molecules to either activate or inhibit enzyme activity.
17. Fat-soluble, your body produces it to respond to sun exposure.
19. Contains three fatty acids bonded to glycerol.
20. A structure that results in the maximum energy point along the reaction path.

1. Forms when electrons in a covalent bond are evenly distributed, or when the electric charges cancel each other out.
2. The code determining the sequence of amino acids is transcribed into this, which moves to ribosomes for protein synthesis.
3. A polysaccharide that's made and stored in animals, and is more highly branched than plant starches.
5. An outer shell electron associated with an atom, which can be transferred to or shared with another atom.
6. Makes up cell membranes, it consists of glycerol, two fatty acids, and a phosphate group.
8. Large ecological areas on Earth, with fauna and flora adapting to their environment.
10. A type of molecule that both fats and oils consist of, also bonded to fatty acids.
12. Binds to enzyme somewhere other than the active site.
16. A polysaccharide found in the exoskeletons of insects.
18. A disaccharide that's usually present in milk.
