Question

ii) Do
you
know that respiration is an exothermic process?
C
We all​

Answer 1

• The food taken by the living beings is ultimately broken down to glucose by the digestive system.

• The glucose so formed is a slowly oxidised to carbon dioxide and water with the release of heat energy.

• Thus, respiration is an exothermic reaction.

• Glucose + Oxygen ---> Carbon dioxide + water + energy.

$\blue{Additional \: information :}$

• The reactions which are accompanied by the evolution of heat are called exothermic reactions OR the reaction in which heat is released along with the formation of products are called exothermic reaction.

• Example - Burning of natural gas and burning of magnesium ribbon.
