Final answer:
Metabolism involves anabolic and catabolic reactions within the body and is not correctly referred to as biotransformation. Biotransformation is a part of metabolism that involves chemical modifications of compounds by an organism.
Step-by-step explanation:
The statement "Metabolism is also called as biotransformation" is false. Metabolism refers to the sum of all anabolic (building) and catabolic (breaking down) reactions in an organism's body. These metabolic processes involve the conversion of food and other substances into energy and building blocks for the body, and the breakdown of these substances to facilitate their elimination. Metabolic processes are constantly taking place in the body to keep you alive. Both anabolism and catabolism occur simultaneously and continuously.
These two opposite processes involve energy metabolism; anabolism requires energy to synthesize larger molecules from smaller ones while catabolism produces energy by breaking down molecules. The metabolites produced during these processes are the end products of metabolism. Therefore biotransformation is a process that is part of metabolism, specifically referring to the chemical modifications made by an organism on chemical compounds, but it is not the same as metabolism itself.
