the question is describe what happens to amino acids inside liver cells.
is the answer the liver sends the amino acids in the blood stream to be distributed to all parts of the body. Excess amino acids are stored in the body after the ammonia from them is removed and converted into urea which is sent by the liver to the kidneys to be excreted.

nope , actually the answer is abit longer and diff ...
1.excess amino acids r deaminated"broken down" by liver to form ammonia , ammonia combines with CO2 to from urea .
2.liver maintains an amino acid pool
3.amino acids r changed into plasma proteins and transported by blood to al body parts , and some amino acids change into liver protien to be used by the liver.
hope i helped
