Question

In plants and microorganisms, amino acid biosynthesis is a matter of synthesizing the appropriate ____ followed by transamination with ____. a. acetyl-CoA derivatives; glutamine b. α-ketoacid; glutamate c. phospho-carbon skeleton; alanine d. nitrogenous base; glutamate e. none are true

Answer 1

Answer:

α-ketoacid; glutamate.

Explanation:

The amino acid synthesis is important for all the living organism. Different organism uses different strategy for the synthesis of amino acid.

The α-ketoacid is generally used in the synthesis of amino acid especially in microorganisms and plants. The transamination of glutamate results results in the formation of particular alpha-keto acid.

Thus, the correct answer is option (b).
