Ornithine
Citrulline
2
Q
Where is the energy for the urea cycle derived?
A
From production of the intermediate products
3
Q
What problem can be caused by an increase in ammonia
A
Neurotoxicity
4
Q
Explain how liver failure can lead to high levels of ammonia in the blood
A
Blood not exposed to enough parenchymal cells to remove the ammonia
Not enough living cells
Blood may bypass the liver due to high resistance (cirrhosis)
5
