Photosynthesis and Cellular Respiration

4. Is a redox-active coenzyme associated with various proteins, which is involved with several important enzymatic reactions in metabolism.
5. Second stage of cellular respiration, in which pyruvic acid is broken down into carbon dioxide in a series of energy-extracting reactions.
7. Conversion of light energy from the sun into chemical energy.
8. The fluid of the chloroplast surrounding the thylakoid membrane; involved in the synthesis of organic molecules from carbon dioxide and water.
9. A flattened membrane sac inside the chloroplast, used to convert light energy into chemical energy.
10. A catabolic process that makes a limited amount of ATP from glucose without an electron transport chain and that produces a characteristic end product, such as ethyl alcohol or lactic acid.
13. Process that requires oxygen.
15. Main energy source that cells use for most of their work.
16. Reactions of photosynthesis that use energy from light to produce ATP and NADPH.
19. Process that releases energy by breaking down glucose and other food molecules in the presence of oxygen.
20. Carrier molecule that transfers high-energy electrons from chlorophyll to other molecules.

1. The breakdown of glucose by enzymes, releasing energy and pyruvic acid.
2. A green pigment found in the chloroplasts of plants, algae, and some bacteria.
3. Series of proteins embedded in a membrane along which energized electrons are transported.
6. Set of reactions in photosynthesis that do not require light; energy from ATP and NADPH is used to build high-energy compounds such as sugar; also called the Calvin cycle.
11. Electron carrier involved in glycolysis.
12. Innermost compartment of the mitochondrion.
14. Process that does not require oxygen.
17. Reactions of photosynthesis in which energy from ATP and NADPH is used to build high-energy compounds such as sugars.
18. A unit of heat used to measure the energy your body uses and the energy it receives from food.
