Metabolism is a set of biochemical reactions taking place inside the organism. It is extremely vital, since it can affect an organism’s life. Metabolism mainly comprises of two processes, namely catabolism and anabolism. The process is involved in the extraction of energy by breaking down the organic matter through digestion and later cellular respiration is called catabolism. Anabolism involves the spending of energy to construct vital components through proteins and nucleic acids, thus allowing an organism to grow, develop and basically stay alive.

The frequency or rate at which energy is released from the organic matter and used to construct vital components in an organism is called metabolic rate. It varies from organism to organism.
