Role of Carbon dioxide During Respiration

Role of Carbon dioxide During Respiration :-
Respiration is a catabolic process which involves the breakdown of food or complex organic molecules into simpler products, with the release of energy. Every cell of a living organism- man, animal and plant, respires. The energy released during respiration is chemical energy. There are two types of respiration- aerobic and anaerobic respiration. This process can take place either in the presence of oxygen (aerobic respiration) or in its absence (anaerobic respiration). Aerobic respiration requires oxygen, so it is called aerobic respiration. During aerobic respiration, complete oxidation of carbohydrates takes place. Glucose is broken down by oxygen to release energy, while carbon dioxide and water are the by-products of the reaction. Aerobic respiration occurs in plants as well as animals and takes place in the mitochondria.

This video explains how to show experimentally that carbon dioxide is given out during respiration.
