# What is a catabolic reaction?

Sep 22, 2017

Biological reactions that involves the breakage of large molecules into smaller ones.

#### Explanation:

Catabolic reactions, or catabolism, is a type of reaction that occurs in living organisms or living cells. It results in the breakage of large or medium molecules into smaller molecules.

A very good example is Glycolysis, which involves the break down of Glucose while using ${O}_{2}$ into $C {O}_{2}$ and energy.

There are many different kinds and examples of catabolism. But all follow the same idea of breaking down molecules into smaller parts.
