Answer: Proteins are broken down into amino acids by protease enzymes.
Explanation:
Protein is an essential nutrients which is needed for growth and development. Protein is the major constituent of hormones, enzymes, eyes, muscles e.t.c.
The protein sources are eggs,beans,meats, milk e.t.c.
Protein digestion start in the stomach.
