What are the differences between aerobic and anaerobic respiration? Name some organisms that use the anaerobic mode of respiration.
Answer
Aerobic Respiration |
Anaerobic Respiration |
1. Aerobic respiration occurs in the presence of oxygen |
1. Anaerobic respiration occurs in the absence of oxygen |
2. Complete oxidation of glucose takes place to form CO 2 and H 2 O |
2. Incomplete oxidation of glucose takes place to form alcohol / lactic acid and CO 2 |
3. It occurs in plant and animal cells |
3. It occurs in anaerobic bacteria and human muscle cells |
4. For each molecule of glucose, 38 molecules of ATP are generated |
4. For each molecule of glucose, only 2 molecules of ATP are generated |
Eg: Humans, Birds, Plants, Animals |
Eg: Yeast, Muscle cells in human tissue, Archaebacteria, E. Coli and lactic acid bacteria |
