Respiration

1. The food group which contains the most energy.
6. Produced in animal cells when no oxygen present.
7. This food group can be readily broken down by the body to produce energy.
8. The number of ATP formed when 2 pyruvate molecules are broken down completely.
9. The process of energy release from food occuring in living cells.
10. This component of food is used to build up muscle.
11. An enzyme controlled process which results in the production of ATP.
13. Total yield of ATP from aerobic respiration.
14. Two of these are formed in the first stage of respiration.
15. Equipment used to measure the energy in food.
18. A product of aerobic respiration.
19. Most common end product of digestion of carbohydrates.
20. Occurs in muscle if lack of oxygen.
21. Can be heat, light, chemical and electrical.
22. Product of plant cells during anaerobic respiration.

2. Respiration without oxygen.
3. Unit that energy in food is measured.
4. A cell process which requires energy.
5. Process of glucose splitting.
8. The bond in ATP which must be broken in order to release energy.
12. The total number of ATP produced during anaerobic respiration.
16. The breakdown of food into small soluble molecules which can be absorbed into blood.
17. Occurs in animal cells during vigouous exercise.
