3. Respiration without oxygen.
5. The number of ATP formed when 2 pyruvate molecules are broken down completely.
7. A cell process which requires energy.
12. Can be heat, light, chemical and electrical.
16. An enzyme controlled process which results in the production of ATP.
18. The total number of ATP produced during anaerobic respiration.
19. The breakdown of food into small soluble molecules which can be absorbed into blood.
21. Product of plant cells during anaerobic respiration.
22. Total yield of ATP from aerobic respiration.
23. Occurs in muscle if lack of oxygen.

1. Two of these are formed in the first stage of respiration.
2. Produced in animal cells when no oxygen present.
4. Unit that energy in food is measured.
6. Equipment used to measure the energy in food.
8. A product of aerobic respiration.
9. The bond in ATP which must be broken in order to release energy.
10. This component of food is used to build up muscle.
11. The process of energy release from food occuring in living cells.
13. Process of glucose splitting.
14. This food group can be readily broken down by the body to produce energy.
15. Most common end product of digestion of carbohydrates.
17. Occurs in animal cells during vigouous exercise.
