Across
- 2. in chloroplasts, one of the stacked, flattened, pigment-containing membranes in which light-dependent reactions occurs
- 4. fluid filled space outside the grana in which light-independent reactions take place
- 5. one of the stacks of pigment-containing thylakoids in a plant’s chloroplast
- 8. in photosynthesis, the major electron carrier involved in electron transport
- 9. catabolic pathway in which organic molecules are broken down to release energy for use by the cell
- 12. a metabolic process that requires oxygen
- 14. metabolic process in which pyruvate is broken down and electron-carrier molecules are used to produce ATP through electron transport
- 16. all of the chemical reactions that occur within an organism.
- 18. series of reactions in which pyruvate is broken down into carbon dioxide inside the mitochondria of cells, also called the tricarboxylic acid cycle and the citric acid cycle
- 19. light-independent reactions during phase two of photosynthesis in which energy is stored in organic molecules as glucose
Down
- 1. anaerobic process; first stage of cellular respiration in which glucose is broken down into two molecules of pyruvate
- 3. metabolic process that does not require oxygen
- 6. energy-carrying biological molecule, which, when broken down, drives cellular activities
- 7. two-phase anabolic pathway in which the sun’s light energy is converted to chemical energy for use by the sell
- 10. study of the flow and transformation of energy in the universe
- 11. ability to do work; energy cannot be created or destroyed, only transformed
- 13. light-absorbing colored molecule, such a chlorophyll and carotenoid, in the thylakoid membranes of chloroplast
- 15. process in which NAD+ is regenerated, allowing cells to maintain glycolysis in the absence of oxygen
- 17. enzyme that converts inorganic carbon dioxide molecules into organic molecules during the final step of the Calvin cycle
