The increase of muscle activity requires more glucose and oxygen to be pumped around the body so more gluscose and oxygen can get to the cells.

What is glycogen?
The place where some glucose is stored from food. It is mainly stored in the liver but is also stored in the muscles. Glucose is taken from these when the muscles are in short supply.
2 of 6
When is anaerobic repiration used?
When there is not enough oxygen. It is the breakdown of glucose but isn't as effective of aerobic repiration.
3 of 6
What is the negative biproduct of anaerobic respiration?
Glucose -> energy + lactic acid. Lactic acid was causes the muscles to get tired and can be painful.

Why do you breath heavily after exercise?
Anaerobic respiration needs oxygen when there isn't any in supply you have to 'repay' the oxygen so the lactic acid is removed by oxidising it with CO2 and water.
5 of 6
Why doesn't your heart rate immediatly slow down after exercise?
The high leves of CO2 and lactic acid are detected by the brain so the breathing and heart rate will stay high to rectify the situation.
