2. List the similarities and differences between aerobic and anaerobic respiration.
The similarities between aerobic and anaerobic respiration are:
(i) Carbon dioxide is produced in both reactions.
(ii) Energy is released in both reactions.
The differences between aerobic and anaerobic respiration are:
| Aerobic | Anaerobic |
| Takes place in the presence of oxygen | Takes place without oxygen |
| Complete break down of food | Partial break down of food |
| Carbon dioxide and water as the end product |
Ethanol, carbon dioxide as the end product(in yeast) |
| Produces more energy | Produces less energy |
