Which of the following are the reactants (the substances used) in aerobic respiration?
glucose and oxygen
water and oxygen
carbon dioxide and glucose
oxygen and water
Aerobic respiration is the process by which organisms use oxygen to turn fuel, such as fats and sugars, into chemical energy.
The reactants (substances used) in aerobic respiration are glucose and oxygen.
To identify the reactants in a chemical reaction, you need to know what substances are used in the process. In the case of aerobic respiration, it is a metabolic process that occurs in the presence of oxygen to produce energy.
Aerobic respiration is represented by the formula:
glucose + oxygen → carbon dioxide + water + energy
From the given options, the correct reactants (substances used) in aerobic respiration are glucose and oxygen. Therefore, the correct answer is "glucose and oxygen."
