Question

Complete the following equation of respiration by selecting the correct option:

Glucose + $\underset{–}{\left(i\right)}$ $\to$ Water + $\underset{–}{\left(ii\right)}$ + Energy

• A. (i) – Mitochondria, (ii) - Alveoli
• B. (i) – Oxygen, (ii) – Glucose oxide
• C. (i) – Carbon dioxide, (ii) – Glucose carbonate
• D. (i) – Oxygen, (ii) - Carbon dioxide

Answer 1

The correct option is D

(i) – Oxygen, (ii) - Carbon dioxide

Our bodies extract the energy in glucose by using oxygen. This process (called respiration) gives out carbon dioxide and water accompanied by the release of energy (in the form of ATP).

Thus the equation is:

Glucose + Oxygen $\to$ Water + Carbon dioxide+ Energy
