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)

The correct option ID

Explanation of the Correot option:

1. Oxygen is required during the process of Aerobic celular respiration in the cell.
2. Aerobic respiration is a process which uses oxygen to breakdown glucose into carbon dioxide and water and release energy in the form of ATP.
3. It can be summarised as

$C_6{H}_{12}{O}_6+{6O}_2⟶6{CO}_2+6H_{2}O+38ATP$

Explanation of the incorrect option:

Option A

1. Carbon dioxide is essential for the survival of most living organisms and cycles in the ecosystem, through respiration (aerobic and anaerobic), photosynthesis and combustion.
2. Carbon dioxide plays an important role in the regulation of earth's temperature, and is one of the greenhouse gases.

Option B

• Nitrogen is an essential macronutrient for plant function and is a key component of amino acids, which form the building blocks of plant proteins and enzymes.

Option C

• Increased levels of carbon monoxide in red blood cells decrease the amount of oxygen rich haemoglobin carries throughout the body.

Final answer: Carbon dioxide gas is used during the process of aerobic cellular respiration.
