RESPIRATION

Respiration is the chemical process, which involves breathing in oxygen , breathing out carbon dioxide & breakdown of food using oxide to release energy.

• All living organisms require energy to carry out various life processes . like nutrition, transport, excretion, reproduction, etc. This energy is stored in the food that we eat .
• In order to break down food to release energy oxidation of food takes place. This reaction takes place in the cells of the body of the organisms.
• The oxygen needed for the oxidation comes from the air that we inhale. This oxygen is then transported to every cell.
• Thus, the process in which food is broken down to release energy is called respiration. During respiration, carbon dioxide and water are released as waste - products.
