उत्तर
Respiration is a process whereby living organisms
- Use oxygen from the air to oxidize food substances mainly glucose, in their body cells.
- Release energy in the form of heat.
- Carbon dioxide and water vapour are also produced and released in the exhaled air.
\[\ce{Glucose + \underset{\text{(in air)}}{Oxygen} -> \underset{\text{Exhaled air}}{Carbon dioxide + Water vapour + Energy(heat)}}\]
Combustion or burning, involves oxidation i.e. combination of substances like fuels with oxygen or air generally resulting in the production of heat and light.
\[\ce{Fuel + \underset{\text{(in air)}}{Oxygen} ->Carbon dioxide + Water vapour + \underset{\text{(heat and light)}}{Energy}}\]
Carbon dioxide is released into the air as a result of all burning.
