2. in plants, the solution in a chloroplast that surrounds the thylakoids
3. is the conversion of light energy into chemical energy stored in organic compounds
4. an enzyme that catalyzes the synthesis of ATP from ADP and phosphate
6. stack of thylakoids in a chloroplast
8. electrons that use energy in electrons to to pump protons across the membrane in the thylakoid membrane or inner mitochondrial membrane
10. the distance between crests in a wave
12. the mixing of carbon dioxide into organic compounds
15. a series of chemical reactions in which the product of one reaction is consumed in the next reaction
17. a substance involved in energy metabolism formed by the breakdown of adenosine triphosphate
18. the portion of light from the sun that is perceived as many colors by the human eye
21. a light-absorbing compound that functions as an accessory pigment in photosynthesis
22. a two part process converting to a three carbon molecule
23. a process that occurs in chloroplasts and mitochondria when the protons move down the concentration gradient

1. light-absorbing pigments used in photosynthesis
3. a molecule in the thylakoid membrane that accepts the electrons that chlorophyll a loses in the light reactions
5. in plants, a compound that absorbs light and imparts color
7. a pigment that absorbs light energy and transfers energy to chlorophyll a in photosynthesis
9. a biochemical pathway in some plants and incorporated in organic acids at night and released in the calvin cycle during the day
11. the second set of reaction in photosynthesis
13. organic molecule that accepts electrons during redox reactions
14. a small pore located on the underside of a leaf
16. the product of a six carbon molecule that splits into a pair of three carbon molecules
19. the first reactions in photosynthesis
20. a unit of several hundred chlorophyll molecules and carotenoid pigment molecules in the thylakoid membrane
