What is glycogen?
Glycogen is a carbohydrate store in aimals, including the muscles, liver and brain of the human body.
1 of 21
How is glycogen used in the body?
Glycogen can be converted rapidly back to glucose during exercise. The glucose is used in anerobic respiration to provide the energy to make your muscles contract.

What are the benefits of exercise?
Your heart and lungs benefit from regular exercise. The heart and lungs both become larger. They both develop a bigger and more efficient blood supply.
3 of 21
What changes occur in your body when you exercise?
Your bodys response to exercise include: an increase in heart rate, in breathing rate and in depth of breathing; glycogen stores in the muscles are converted to glucose for cellular respiration; the blood flow to the muscle increases.

Why do muscles use anaerobic respiration to obtain energy?
If muscles work hard for a long period of time they become fatigued and don't contract efficiently. If they don't get enough oxygen they will respire anaerobically.

What is the anaerobic respiration equation?
glucose --> lactic acid (+ energy)

Why is less energy released by anaerobic respiration than aerobic respiration?
Anaer

What is the anaerobic respiration equation?
glucose --> lactic acid (+ energy)
9 of 21
Why is less energy released by anaerobic respiration than aerobic respiration?
Anaerobic respiration is not as efficient as aerobic respiration. This is because the glucose molecules are not broken down complet

What is the anaerobic respiration equation?
glucose --> lactic acid (+ energy)
11 of 21
Why is less energy released by anaerobic respiration than aerobic respiration?
Anaerobic respiration is not as efficient as aerobic respiration. This is because the glucose molecules are not broken down completely. So far less energy is released in anaerobic respiration than aerobic respiration.

Why is less energy released by anaerobic respiration than aerobic respiration?
Anaerobic respiration is not as efficient as aerobic respiration. This is because the glucose molecules are not broken down completely. So far less energy is released in anaerobic respiration than aerobic respiration.

What is the oxygen debt repayment equation?
lactic acid + oxygen --> carbon dioxide + water
16 of 21
What is an oxygen debt?
The amount of oxygen needed to break down the lactic acid to carbon dioixde

What is an oxygen debt?
The amount of oxygen needed to break down the lactic acid to carbon dioixde and water is known as an oxygen debt.
