Respiration Review

5. the first step of respiration, which breaks glucose into two pyruvate molecules
6. indicates that oxygen is not used
8. fermentation release much _______ energy than aerobic respiration
9. the rate of photosynthesis is affected by how much of this gas is available
10. a compound formed in muscle tissue when fermentation occurs. It causes muscle soreness
12. a process of respiration that occurs when oxygen is not available
14. a chemical reaction of respiration which only occurs when oxygen is present and creates large amounts of ATP
16. the energy for the photosynthesis reaction comes from what?

1. the process of respiration which creates ATP and NADH (energy)
2. photosynthesis and respiration together recycle this element in the environment
3. the process that breaks down food to obtain energy for an organism
4. the process in photosynthesis that builds glucose molecules
7. the process that uses sunlight to combine carbon, hydrogen and oxygen to make sugars
11. the molecule formed through respiration that stores energy for use y the organism
13. fermentation by yeast produces this alcohol
15. indicates that oxygen is used
