Q.2 List the similarities and differences between aerobic and anaerobic respiration.


Answer :

Similarities:


(1) In both aerobic and anaerobic respiration, the food is broken down to release energy.

(2) Both occur inside the cells.

(3) Both supply by-products.

(4) Both use glucose as the starting molecule. This is called the substrate.

(5) Both respiration produce ATP.

(6) Food is oxidized in both cases and energy is released.

Differences:

(1) Aerobic respiration takes place in the presence of oxygen while anaerobic respiration takes place in the absence of oxygen.

(2) Aerobic respiration's products are CO2 and H2O while anaerobic respiration's products are CO2 and alcohol.

(3) Aerobic is a slow process while anaerobic is a fast process.

(4) Aerobic respiration is caused in animals and plant cells while anaerobic respiration is caused in human cells, yeast, bacteria, etc.

(5) Aerobic respiration releases more energy than anaerobic respiration.
