- Cellular Respiration in Muscles during Physical Activity
- muscle cells will respire aerobically whilst the oxygen supply is adequate
- e.g: walking requires little energy so it will be supplied aerobically
- intense sporting activity
- such as: 100m sprint
- can quickly increase the level of oxygen required causing the depth and frequency of breathing and heart rate to increase
- can quickly increase the level of oxygen required causing the depth and frequency of breathing and heart rate to increase
- such as: 100m sprint
- carbon dioxide will build up
- which will increase the acidity of the muscle cells
- before it is removed by the circulatory system
- which will increase the acidity of the muscle cells
- as exercise continues...
- oxygen levels in the blood will decrease
- carbon dioxide levels will increase
- if oxygen can't be supplied quick enough...
- cells will respire anaerobically
- causing a build up of lactic acid
- inside muscle cells
- in the blood
- a build up of lactic acid can cause...
- muscle fatigue
- cramps
- causing a build up of lactic acid
- cells will respire anaerobically
- to avoid damage to cells...
- lactic acid has to be broken down to...
- carbon dioxide and water
- immediately after exercise has finished
- requires oxygen
- extra oxygen needed is called oxygen debt
- body continues to breathe deeply for some time
- after vigorous exercise has finished
- oxygen debt is paid back only after all lactic acid has broken down
- body continues to breathe deeply for some time
