Question

Give reason:

Respiration is an exothermic reaction.

Answer 1

Respiration is considered an exothermic reaction because, in respiration, the oxidation of glucose takes place, which produces a large amount of heat energy.

\[\ce{C6⁢H12O6_{⁢(aq)} + 6O2⁢_{(g)} -> 6CO2_{⁢(g)} + 6H2O_{⁡(l)} + energy}\]
