Detailed explanation-1: -Summary. Ammonia is the waste produced by metabolism of nitrogen-containing compounds like proteins and nucleic acids.

Detailed explanation-2: -Protein catabolism is the breakdown of proteins into absorbable monomers for further degradation or reassembly. Protein catabolism in the intestinal lumen is important for several reasons, one of which is mobilizing essential amino acids for absorption.

Detailed explanation-3: -Uric acid is a waste product that results from the breakdown of purine, a nucleic acid. Uric acid is made in the liver and excreted by the kidneys.

Detailed explanation-4: -Protein catabolism produces amino acids that are used to form bacterial proteins or oxidized for to meet the energy needs of the cell.

Detailed explanation-5: -Catabolism of amino acids can be broadly categorized into two processes: the breakdown of amino acids to carbohydrate precursors and potentially leading to the formation of glucose; and transformations leading to acetyl CoA that result in the potential formation of ketone bodies.
