Question

Respiration is a slow combustion process.

• A. True
• B. False

Answer 1

The correct option is A True

1. The process of burning a substance in the presence of oxygen and thus release of heat (energy) is called combustion.
2. Respiration, also, is a process in which food materials are burned very slowly with controlled release of heat (energy) and in presence of oxygen producing carbon dioxide ($\mathit{C}{\mathit{O}}_{\mathbf{2}}$), water, and energy.
3. So, respiration is a slow combustion.
   Hence, the given statement is true.
