Classification
Nouns denoting natural processes.
Examples
- The process of catabolism involves the breakdown of complex molecules into simpler ones, releasing energy that can be used by the cell.
- In humans, the catabolism of glucose produces energy that is used to power muscle contractions and other cellular activities.
- Catabolism of proteins involves the breakdown of polypeptide chains into individual amino acids, which can then be reused to synthesize new proteins.
- The catabolism of fatty acids in the liver produces acetyl-CoA, a molecule that can be used to generate energy through the citric acid cycle.
- Dysregulation of catabolism can lead to metabolic disorders, such as diabetes, where the body is unable to properly break down glucose and release energy.
