Across
- 4. The sequence of reactions by which most living cells generate energy during the process of aerobic respiration. It takes place in the mitochondria, consuming oxygen, producing carbon dioxide and water as waste products, and converting ADP to energy-rich ATP.
- 6. Compound used by cells to store and release energy.
- 7. Relating to, involving, or requiring an absence of free oxygen.
- 8. The chemical breakdown of a substance by bacteria, yeasts, or other microorganisms, typically involving effervescence and the giving off of heat.
- 10. An organism that is able to form nutritional organic substances from simple inorganic substances such as carbon dioxide.
- 11. A green pigment, present in all green plants and in cyanobacteria, responsible for the absorption of light to provide energy for photosynthesis.
- 14. The process by which green plants and some other organisms use sunlight to synthesize foods from carbon dioxide and water.
Down
- 1. The chemical process that generates most of the energy in the cell, supplying molecules needed to make the metabolic reactions (see metabolism) of an organism run.
- 2. Relating to, involving, or requiring free oxygen.
- 3. Innermost compartment of the mitochondrion.
- 5. The amount of energy needed to raise the temperature of 1 gram of water by 1 degree Celsius.
- 9. A coenzyme that occurs in many living cells and functions as an electron acceptor.
- 12. An organism deriving its nutritional requirements from complex organic substances.
- 13. The breakdown of glucose by enzymes, releasing energy and pyruvic acid.
- 14. Light-absorbing molecules used by plants to gather the sun’s energy.
