What is the function of enzymes in protein metabolism?

Enzymes play a key role in protein metabolism by helping chemical reactions happen quickly and correctly inside the body.

Here’s a explanation:

1. Protein digestion:
   Enzymes like pepsin, trypsin, and peptidase break down large protein molecules into smaller amino acids during digestion.
2. Amino acid conversion:
   Other enzymes help modify amino acids — for example, by removing or transferring amino groups (processes like deamination and transamination).
3. Energy production:
   Enzymes help convert the remaining carbon parts of amino acids into molecules that enter energy pathways (like the Krebs cycle) to make ATP.
4. Protein synthesis:
   Enzymes are also needed to join amino acids together to make new proteins in cells.

In short:
Enzymes in protein metabolism break down proteins, convert amino acids, and build new proteins — making sure the whole process runs smoothly and efficiently.
