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 |

The similarities and differences between aerobic and anaerobic respiration are as follows:
SIMILARITIES:
1) They both use glucose as the starting molecule.
2) Food is oxidized in both cases and energy is released.
DIFFERENCES:
1) Carbon dioxide and water are the end products of aerobic respiration, while alcohol or lactic acid is the end product of anaerobic respiration.
2) Aerobic respiration is more efficient than anaerobic respiration.
