Urea cycle
From Citizendium, the Citizens' Compendium
In biology, the urea cycle (also called the ornithine cycle) breaks down amino acids.[1]
The urea cycle produces:
- fumarate which enters the citric acid cycle to produce energy.
- ornithine which re-enters the urea cycle.
- urea which is toxic and is excreted.
