Summary Introduction
Introduction:
Respiration is the process of taking in of oxygen and exhaling out of carbon dioxide. It also involves the breakdown of glucose and thereby releases energy by the oxidation of food. It takes place by the series of the cycle. The three steps are glycolysis, intermediate cycle, citric acid cycle, and electron transport cycle.
