Answer
Energy can be obtained from amino acids by hepatocytes-- and other cells of the body -- through the processes of the Krebs cycle. However, before amino acids can enter the Krebs cycle, they must be deaminated, that is, their amino groups must be removed
Work Step by Step
The waste product from deamination is ammonia (NH3). Ammonia is very toxic, but hepatocytes transform ammonia into urea, a harmless substance. Urea is excreted in urine.
