Question

During aerobic respiration, glucose is broken down by using _______ gas.

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

Answer 1

The correct option is A Oxygen

Oxygen is required during the process of cellular respiration in the cell. Aerobic respiration is a process which utilises oxygen to breakdown glucose into carbon dioxide and water and release energy in the form of ATP.
It can be summarised as:
$C_6{H}_{12}{O}_6+6O_2\to 6{\mathrm{CO}}_2+6H_{2}O+38\mathrm{ATP}$
