I had been asked this question during an online interview.

I want to ask this question from Metabolic Fates of Amino Groups topic in chapter Amino Acid Oxidation and the Production of Urea of Biochemistry

Answer 1

Correct choice is (a) Amino transferases

The best I can explain: The first step in the catabolism of most L-amino acids once they have reached the liver is removal of the α-amino groups promoted by enzymes called amino transferases or trasaminases.
