The true statement about the equation of respiration is:
The mass of the reactants is the same as the mass of the products; option C.
<h3>What is respiration?</h3>
Respiration is the process by which living organisms break down large molecules such as glucose into smaller molecules such a carbon dioxide and water to release energy in the form of ATP.
Respiration are of two types in living organisms:
- Aerobic respiration which requires oxygen
- anaerobic respiration that does not require oxygen
The equation of aerobic respiration is given below:
- C₆H₁₂O₆ + 6 O₂ → 6 CO₂ + 6 H₂O + energy
In the given equation above, glucose reacts i the presence of oxygen is broken down into carbon dioxide and water and energy is released.
According to the law of conservation of mass, the mass of reactants is equal to the mass of the products.

Respiration describes the process that living cells use to release energy by combining sugar and oxygen. The primary chemical changes that happen during respiration are shown in the equation below.
C₆H₁₂O₆ + 6 O₂ → 6 CO₂ + 6 H₂O + energy
