When the amine group is removed, the carbon-containing component of amino acids can be ) used to make dnab) used for energyc) transformed into muscle massd) converted to protein

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

d. changes in climate and historical records
