Verified step by step guidance

Understand the role of amino acids in metabolism: Amino acids are the building blocks of proteins and can be used in catabolic reactions to produce energy.

Recognize the process of deamination: Before amino acids can be used in catabolic reactions, they must undergo deamination, which is the removal of an amino group.

Explain the significance of deamination: Deamination converts amino acids into keto acids, which can enter metabolic pathways such as the citric acid cycle.

Identify the fate of the removed amino group: The amino group is typically converted into ammonia, which is then processed into urea in the liver for excretion.

Clarify why other options are incorrect: Amino acids are not converted into nucleotides, phosphorylated, or oxidized to form glucose before catabolism; deamination is the necessary step.
