- Respiration
- Aerobic Respiration
- Takes place in the presence of oxygen
- glucose + oxygen --> carbon dioxide + water + energy
- takes place in the mitochondria
- Energy released used to......
- build larger molecules from smaller ones
- enable muscles to contract
- maintain a constant temperature
- make proteins from amino acids
- Changes during exercise
- Heart rate increases
- These changes increase...
- flow of blood to the muscles
- supply of oxygen and sugar
- the rate of carbon dioxide removal
- These changes increase...
- The arteries supplying the muscles dilate (widen)
- These changes increase...
- flow of blood to the muscles
- supply of oxygen and sugar
- the rate of carbon dioxide removal
- These changes increase...
- The rate and depth of breathing increases
- Heart rate increases
- Anaerobic Respiration
- the incomplete breakdown of glucose
- less energy is released
- causes muscle fatigue
- deep breathing is required to oxidise the lactic acid to carbon dioxide and water
- the oxygen required to do this is called oxygen debt
- deep breathing is required to oxidise the lactic acid to carbon dioxide and water
- Waste product is lactic acid
- Removed by the blood flowing through the muscles
- Aerobic Respiration
