The purpose of deamination in the liver is to:
A)use excess amino acids for energy production
B)use excess amino acids for protein synthesis
C)synthesize the essential amino acids
D)synthesize the nonessential amino acids

Question

Quizplus · Accepted Answer

Deamination in the liver involves the removal of the amino group (-NH2) from amino acids and converting it into ammonia (NH3) and then urea, which is excreted in urine. This process allows the liver to use the carbon skeleton of the amino acids for energy production or for synthesis of glucose or fatty acids. Therefore, choice A is the correct answer as it describes the purpose of deamination in the liver. Choices B, C, and D are incorrect as they describe processes that involve the synthesis of amino acids, which is not the purpose of deamination.
