What is a difference between the oxidation of coal when it is burned and the oxidation of glucose during cellular respiration? a) cellular respiration is an endothermic reaction. b) energy is released only during the burning of fossil fuels c) complete oxidation takes place only during the burning of fossil fuels d) energy is produced and stored during cellular respiration.

Ans. (D). Energy is produced and stored during cellular respiration.

Oxidation of glucose during cellular respiration is better than burning of coal in the presence of oxygen. It is because burning coal generates heat, which is not generally useful and cannot be captured by cells as energy source.

On the other hand, cellular respiration involves complete oxidation of glucose, which provides so much energy. This energy is stored by the cell for its cellular activities.

Thus, the correct answer is option (D).
