Question

What is aerobic and anaerobic respiration?

Answer 1

Respiration:

1. Respiration is the process of releasing energy from the breakdown of glucose.
2. Respiration takes place in every living cell, all of the time and all cells need to respire in order to produce the energy that they require.
3. There are two main types of respiration, aerobic and anaerobic.

Aerobic respiration:

1. Aerobic respiration is the respiration where glucose is broken down by oxygen to release energy along with carbon dioxide and water being produced as by-products of the reaction.
2. Glucose + Oxygen $\to$ Carbon dioxide + Water + Energy.

3. The energy produced in this type of respiration is more.

4. The glucose is completely broken down into water and carbon dioxide.

5. It takes place in animals and plants.

Anaerobic respiration:

1. Anaerobic respiration is the respiration which occurs in the absence of oxygen to produce the energy.
2. It occurs in yeast cells in which alcohol is produced.
3. It also occurs in muscles of our body when we do excess workout which causes the temporary lack of the oxygen for muscles.
4. Glucose $\to$ Ethanol + Carbon dioxide + Energy (In yeast cells).
5. The muscle cells then start doing anaerobic respiration and produce lactic acid.
6. Glucose $\to$ Lactic acid + Energy (in muscles).
7. There is partial breakdown of glucose.
