Across
- 4. an organelle found in large numbers in most cells, in which the biochemical processes of respiration and energy production occur. It has a double membrane, the inner layer being folded inward to form layers
- 6. relating to, involving, or requiring an absence of free oxygen.
- 9. each of a number of flattened sacs inside a chloroplast, bounded by pigmented membranes on which the light reactions of photosynthesis take place, and arranged in stacks or grana.
- 11. an organism, typically a bacterium, that derives energy from the oxidation of inorganic compounds
- 12. the breakdown of glucose by enzymes, releasing energy and pyruvic acid.
- 13. an organism that is able to form nutritional organic substances from simple inorganic substances such as carbon dioxide.
- 15. the process by which green plants and some other organisms use sunlight to synthesize foods from carbon dioxide and water. Photosynthesis in plants generally involves the green pigment chlorophyll and generates oxygen as a byproduct.
Down
- 1. set of chemical reactions that take place in chloroplasts during photosynthesis
- 2. a colorless syrupy organic acid formed in sour milk and produced in the muscle tissues during strenuous exercise
- 3. composed of adenosine and two phosphate groups that is formed in living cells as an intermediate between ATP and AMP and that is reversibly converted to ATP for the storing of energy by the addition of a high-energy phosphate group
- 5. The chemical process that generates most of the energy in the cell
- 7. a green pigment, present in all green plants and in cyanobacteria, responsible for the absorption of light to provide energy for photosynthesis. Its molecule contains a magnesium atom held in a porphyrin ring
- 8. a plastid that contains chlorophyll and in which photosynthesis takes place.
- 10. relating to, involving, or requiring free oxygen.
- 14. is the energy currency of life.
