Question

Which gas is used during the process of aerobic cellular respiration?

• A. Oxygen
• B. Carbon dioxide
• C. Nitrogen
• D. Carbon monoxide

Answer 1

Answer: (A)

Aerobic respiration:

1. Aerobic respiration is a process which utilises oxygen to breakdown glucose into carbon dioxide and water and release energy in the form of ATP.
2. This type of respiration is common in most of the plants and animals, birds, humans, and other mammals.

Oxygen gas is used during aerobic respiration:

1. Oxygen is required during the process of aerobic cellular respiration in the cell.
2. The cellular energy in the form of ATP is formed by the breaking of the food with the help of oxygen.
3. The reaction can be represented as follows:
4. Glucose + oxygen $⟶$ carbon dioxide + water + energy.

$C_6{H}_{12}{O}_6+{6O}_2⟶{6CO}_2+{6H}_{2}O+ATP$ .
