CORRECT OPTION: TRANSAMINATION
EXPLANATION:
PHOSPHORYLATION:
It is the process of adding a phosphoryl group to a organic compound. Irrelevant here.
TRANSAMINATION:
A process in which amino groups are transferred into ketoacid to form newer amino acids.This happens if excess of protein is consumed.
UREA CYCLE:
A cycle of conversion of highly toxic ammonia into less toxic urea for excretion.
DEAMINATION:
Removal of amino groups from amino acids and converts them into ammonia.
The important process when a new amino acids are produced in the body:
- TRANSAMINATION

2. Proteins degradation provides free amino acids, which may be further degraded by deamination and transamination in order to synthesis new compounds, produce energy, or eliminate waste. Provide a brief description for each of the possible fates of free amino acids with specific reference to biochemical reactions and state how the products of these reactions may are utilized. 3. Consider the amount the ATP yield from two different 6-carbon biomolecules: fructose and caproic acid. With specific reference to the catabolic...

Amino acids can be categorized according to the body's ability to synthesize them. Both essential and nonessential amino acids are necessary for life, but the human body is unable to synthesize some amino acids. Different pathways enable synthesis of nonessential amino acids from five precursors: pyruvate, 3-phosphoglycerate, oxaloacetate, a-ketoglutarate, and phenylalanine. Many of these pathways include a process called transamination, which is a reaction between an amino acid and an alpha-keto acid. Some non essential amino acids are synthesized in...

Additional energy can be provided and body fat can be made when amino acids are converted to acetyl COA Some amino acids enter the TCA cycle directly and therefore, are allowed to continue in the metabolic cycle to generate energy and glucose The availability of nitrogen allows the body to use acetyl COA and glycerol to make some non-essential amino acids.
