What are the different types of respiration? |
Aerobic Anaerobic |
|
|
How does aerobic respiration work? |
Chemical reactions occur that use glucose and oxygen and release energy Glucose + oxygen --> carbon dioxide + water + energy C6H12O6 + 6O2 --> 6CO2 + 6H2O + energy |
|
|
How does anaerobic respiration work? |
Incomplete breakdown of glucose occur, which causes a build-up of lactic acid The lactic acid needs to be oxidised to carbon dioxideand water Much less energy is released because of the incomplete breakdown |
|
|
What happens during aerobic respiration? |
The heart rate increases, increasing blood flow. The rate anddepth of breathing increase Glycogen stored in the muscles is converted back toglucose This increases the supply of glucose and oxygen to, and increase the rate ofremoval of carbon dioxide from, the muscles |
|
|
What happens during anaerobic respiration? |
Muscles become fatigued and stopcontracting efficiently One cause of muscle fatigue is the build-up of lacticacid in the muscles Blood flowing through the muscles eventually removes thelactic acid |
|
|
What are the product of anaerobic respiration in plant cells and some microorganisms? |
Anaerobic respiration in plant cells and in some microorganisms produces ethanol andcarbon dioxide |
