Biology Review

4. A liquid produced during muscle contraction as a product of anaerobic glucose metabolism, prepared usually by fermentation.
6. Organelles found in large numbers in most cells, in which the biochemical processes of respiration and energy production occur.
7. ions/Positively charged atoms of hydrogen; that is to say, normal hydrogen atomic nuclei.
8. Stable negatively charged elementary particles with a small mass that are a fundamental constituent of matter and orbit the nucleus of an atom.
10. A simple sugar, C6H12O6, that is an important energy source in living organisms and is a component of many carbohydrates.
11. The sequence of reactions by which most living cells generate energy during the process of aerobic respiration.
14. a colorless odorless gas that is the most abundant element, forms compounds with most others, is essential for plant and animal respiration, and is necessary in most cases for combustion.
15. A process in which electrons are transferred from one compound to another with a release of energy occurring in the production of ATP.
18. The breakdown of glucose by enzymes, releasing energy and pyruvic acid.

1. Relating to, involving, or requiring free oxygen.
2. The general term for an enzyme that can synthesize adenosine triphosphate (ATP) from adenosine diphosphate (ADP).
3. The process of producing ATP by breaking down carbon-based molecules when oxygen is present.
5. A series of reactions that take place in photosynthesis by which carbon dioxide is converted to glucose.
9. The breakdown of carbohydrates by microorganisms.
12. An organelle found in large numbers in most cells, in which the biochemical processes of respiration and energy production occur.
13. A compound consisting of an adenosine molecule bonded to three phosphate groups, present in all living tissue.
16. A plastid that contains chlorophyll and in which photosynthesis takes place.
17. Relating to, involving, or requiring an absence of free oxygen.
