Across
- 5. Respiration/the process that releases energy by breaking down food molecules in the presence of oxygen.
- 7. process that molecules tend to from an area where they are more concentrated to an area where they are less concentrated.
- 9. energy from food molecules in the absence of oxygen.
- 11. of the principal chemical compounds that living things use to store energy.
- 13. not require oxygen.
- 14. energy from the foods they consume (animals).
- 15. principle pigment.
- 16. region out the thylakoid membranes.
- 18. gather the suns energy with light-absorbing molecules.
- 19. photosynthetic membranes.
Down
- 1. first stage of cellular respiration.
- 2. second stage of cellular respiration.
- 3. Reactions/requires light.
- 4. their own food (plants).
- 6. water molecules to pass easily through most biological membranes.
- 8. use the energy of sunlight to convert water and carbon dioxide into oxygen and high-energy carbohydrates.
- 10. Calvin Cycle/uses ATP and NADPH from the light-dependent reactions to produce high-energy sugars.
- 12. oxygen.
- 17. Synthase/protein that membranes contain.
