- 2. metabolic processes that do not require oxygen.
- 6. is a green pigment that is present in most plant cells, that gives plants its characteristic color, and that reacts with sunlight, carbon dioxide, and water to form carbohydrates.
- 7. is a substance that gives another substance or a mixture of its color.
- 8. clusters of pigments that are embedded in the membranes of disk-shaped structures.
- 10. cycle a series of biochemical reactions that convert pyruvic acid into carbon dioxide and water; it is the major pathway of oxidation in animal, bacterial, and plant cells, and it releases energy.

- 1. metabolic processes that require oxygen.
- 3. Cycle is a biochemical pathway of photosynthesis in which carbon dioxide is converted into glucose using ATP.
- 4. respiration is the process by which cells produce energy from carbohydrates; atmospheric oxygen combines with glucose to form water and carbon dioxide.
- 5. is the process by which plants, algae, and some bacteria use sunlight, carbon dioxide, and water to produce carbohydrates and oxygen.
- 9. organisms that must get energy from food instead of directly from the sunlight of inorganic substances.
