|
Catabolism occurs during protein synthesis.
|
|
Catabolic reactions release energy that can be captured in the form of ATP
|
|
An example of a catabolic process is DNA replication.
|
|
Catabolism is the synthesis of complex molecules from simpler molecules through hydrolysis.

Detailed explanation-1: -Catabolic reactions give out energy. They are exergonic. In a catabolic reaction large molecules are broken down into smaller ones. For example, the reverse of the condensation reactions described above, i.e. hydrolysis reactions, are catabolic.
Detailed explanation-2: -Molecular energy stored in the bonds of complex molecules is released in catabolic pathways and harvested in such a way that it can be used to produce ATP. Other energy-storing molecules, such as fats, are also broken down through similar catabolic reactions to release energy and make ATP (Figure 11.2.
Detailed explanation-3: -Some catabolic pathways can capture that energy to produce ATP, the molecule used to power all cellular processes. Other energy-storing molecules, such as lipids, are also broken down through similar catabolic reactions to release energy and make ATP.
