Across
- 4. 6CO2 + 6H2O ------> C6H12O6 + 6O2
- 7. A simple sugar that is an important source of energy. (C6H12O6)
- 9. first step of cellular respiration the energy of glucose, in which a molecule of glucose is broken into two molecules of pyruvic acid and 2 ATP molecules
- 13. of photosynthesis that use energy from light to produce ATP and NADPH
- 14. (CO2) A gas that is taken in by plants during photosynthesis and given off by organisms during cellular respiration.
- 15. (Adenosine Diphosphate) The molecule that remains when a phosphate group is removed from ATP. It has a low amount of energy.
- 17. An organelle found in plant and algae cells where photosynthesis occurs.
Down
- 1. process by which plants and some other organisms use light energy to convert water and carbon dioxide into oxygen and high-energy carbohydrates such as sugars and starches
- 2. set of reactions in photosynthesis that do not require light; energy from ATP and NADPH is used to build high-energy compounds such as sugar; also called the Calvin cycle
- 3. second stage of cellular respiration, in which pyruvic acid is broken down into carbon dioxide, 2 ATP molecules, 2 FADH2 molecules, and 6 NADH molecules in a series of energy-extracting reactions.
- 5. (O2) A gas that is taken in by organisms during cellular respiration and give off as a waste product by plants during photosynthesis.
- 6. third stage of cellular respiration in which NADH and FADH2 are broken down by a series of reactions to form water and 34 ATP.
- 8. C6H12O2 + 6O2 ------> 6CO2 + 6H20 + Energy (ATP)
- 10. Powerhouse of the cell, organelle that is the site of ATP (energy) production during cellular respiration.
- 11. Process that releases energy by breaking down glucose and other food molecules in the presence of oxygen
- 12. (H2O) A liquid taken in by plants during photosynthesis and given off by organisms during cellular respiration.
- 16. (adenosine triphosphate) main energy source that cells use for most of their work.
