Question

When the amine group is removed, the carbon-containing component of amino acids can be ______.A) used to make DNAB) used for energyC) transformed into muscle massD) converted to protein

Answer 1

Answer: option B) used for energy

Explanation:

Amino acids are metabolized first by being deaminated (amino group, NH3 removed) leaving a carbon-containing compound as product.

This product then enters the citric acid cycle to yield energy in form of ATP and/or reducing equivalents like NADH, FADH.

A good example is Glutamic acid, that yields α-keto glutarate when the amine group is removed. This α-keto glutarate is directed to the CITRIC ACID CYCLE for ENERGY production.

So, the carbon-containing component of amino acids can be used for energy
