Bioenergetics

4. An organelle found in plant and algae cells where photosynthesis occurs.
7. third stage of cellular respiration in which NADH and FADH2 are broken down by a series of reactions to form water and 34 ATP.
9. A gas that is taken in by plants during photosynthesis and given off by organisms during cellular respiration.
13. reactions of photosynthesis that use energy from light to produce ATP and NADPH
14. Process that releases energy by breaking down glucose and other food molecules in the presence of oxygen
16. 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
17. 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

1. 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.
2. A gas that is taken in by organisms during cellular respiration and give off as a waste product by plants during photosynthesis.
3. A liquid taken in by plants during photosynthesis and given off by organisms during cellular respiration.
5. main energy source that cells use for most of their work.
6. equation 6CO2 + 6H2O = C6H12O6 + 6O2
8. Respiration equation C6H12O2 + 6O2 = 6CO2 + 6H20 + Energy (ATP)
10. Powerhouse of the cell, organelle that is the site of ATP (energy) production during cellular respiration.
11. The molecule that remains when a phosphate group is removed from ATP. It has a low amount of energy.
12. A simple sugar that is an important source of energy.
15. 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
