• D. Proteolysis.

Answer: (C)

Verified step by step guidance

1. Understand the concept of nonessential amino acids: These are amino acids that the body can synthesize on its own, unlike essential amino acids which must be obtained through the diet.
2. Learn about transamination: This is the process by which the body transfers an amino group (-NH₂) from one molecule, typically an amino acid, to a keto acid. This reaction is catalyzed by enzymes called aminotransferases.
3. Recognize the role of transamination in amino acid synthesis: During transamination, the amino group is transferred to a keto acid, converting it into a new amino acid. This is how nonessential amino acids are efficiently produced.
4. Differentiate transamination from other processes: Hydrolysis involves breaking chemical bonds with water, deamination involves removing an amino group without transferring it, and proteolysis refers to the breakdown of proteins into smaller peptides or amino acids.
5. Apply this knowledge to identify transamination as the correct process for producing nonessential amino acids by transferring an amino group from one molecule to another.
