Introduction:
The biochemical process that occurs within the living organisms is important for their survival. Metabolism has two parts namely, anabolism and catabolism. Anabolism is the formation or synthesis of new complex molecules from simpler ones while in catabolism, breakdown of complex molecules into the smallest units occurs.
