What is anabolism and catabolism ? explain
Answers
Anabolism
Anabolism is one of the processes in metabolism. It is a constructive process. It is defined as simple molecules that combine to form complex molecules or the generation of complex molecule from simple molecules. It usually requires energy. This process produces complex molecules that can be used to store energy. It is the reverse process of catabolism. The energy used here is derived from the catabolic reactions. Energy for these reactions can be stored in the form of Adenosine Tri Phosphate (ATP) molecule.
Example
Carbohydrates and proteins are the molecules which results from the anabolic reaction.
Catabolism
It is a destructive process in which break down of complex molecules and formation of simple molecules takes place. This process proceeds with release of energy. The released energy acts as a driving force for the catabolic reaction. These reactions are catalyzed by enzymes.
Example:
Digestion is a process in which macromolecules like proteins carbohydrates are broken down into their simple molecules like amino acids and sugars etc.
Note: Two processes namely anabolism and catabolism constitute the process called metabolism. Metabolism is the sum or total of all chemical reactions in a living organism (combines both anabolic and catabolic process).
