The amino group of amino acids is eliminated by which pathway?Group of answer choicesre-aminationbeta oxidationKrebs cyclede-aminationglycolysis

Break Down the Problem

1. Identify the amino group elimination process in amino acids.
2. Match the process with the correct pathway from the provided answer choices.

Relevant Concepts

• De-amination is a biochemical process where an amino group ($-NH_2$) is removed from an amino acid.
• Other options do not specifically pertain to the elimination of the amino group from amino acids.

Analysis and Detail

1. Re-amination involves the addition of an amino group rather than the elimination.
2. Beta Oxidation relates to the breakdown of fatty acids and does not involve amino groups.
3. Krebs cycle (or citric acid cycle) is a metabolic pathway for the oxidation of acetyl-CoA; while it does involve amino acids, it doesn’t specifically eliminate the amino group.
4. De-amination specifically denotes the removal of the amino group from amino acids, converting them into intermediates that can enter various metabolic pathways.
5. Glycolysis is primarily the breakdown of glucose and does not involve amino group modulation.

Verify and Summarize

Upon analyzing the options, de-amination clearly stands out as the pathway responsible for the elimination of the amino group in amino acids.

Final Answer

De-amination is the pathway by which the amino group of amino acids is eliminated.
