FAQs on What is Anaerobic Respiration?

Question 1

1. What is anaerobic respiration?

Accepted Answer

Ans. Anaerobic respiration is a type of cellular respiration that occurs in the absence of oxygen. It is a process by which cells break down glucose to produce energy without the need for oxygen.

Question 2

2. How does anaerobic respiration differ from aerobic respiration?

Accepted Answer

Ans. Anaerobic respiration differs from aerobic respiration in terms of the final electron acceptor. In anaerobic respiration, the final electron acceptor is an inorganic molecule other than oxygen, while in aerobic respiration, the final electron acceptor is oxygen.

Question 3

3. What are the products of anaerobic respiration in humans?

Accepted Answer

Ans. In humans, anaerobic respiration produces lactic acid as a byproduct. This can occur during intense exercise when the body cannot supply enough oxygen to the muscles, leading to the buildup of lactic acid.

Question 4

4. Can anaerobic respiration occur in all organisms?

Accepted Answer

Ans. No, anaerobic respiration cannot occur in all organisms. While some organisms, like humans, can undergo anaerobic respiration under certain conditions, others, such as plants, rely primarily on aerobic respiration and do not carry out anaerobic respiration.

Question 5

5. What are some examples of organisms that undergo anaerobic respiration?

Accepted Answer

Ans. Some examples of organisms that undergo anaerobic respiration include certain bacteria, fungi, and human muscle cells. These organisms can switch to anaerobic respiration when oxygen is limited or unavailable, allowing them to continue producing energy.
