Question 2. What is the action of pepsin?
Question 3. How do you classify amino acids?
​

Answer 1

Answer:

$\huge \underline \red{★ Answer❀✿°᭄★}$

1. Pepsin

epsinProtein digestion occurs in the stomach and the duodenum through the action of three main enzymes: pepsin, secreted by the stomach, and trypsin and chymotrypsin, secreted by the pancreas.

2. Pepsin is an endopeptidase that breaks down proteins into smaller peptides. It is produced in the chief cells of the stomach lining and is one of the main digestive enzymes in the digestive systems of humans and many other animals, where it helps digest the proteins in food.

3. Amino acids are usually classified by the properties of their side chain into four groups. The side chain can make an amino acid a weak acid or a weak base, and a hydrophile if the side chain is polar or a hydrophobe if it is nonpolar.

Answer 2

Answer:

1.PEPSIN

Explanation:

It is produced by the stomach cells called "chief cells" in its inactive form pepsinogen, which is a zymogen. Pepsinogen is then activated by the stomach acid into its active form, pepsin. Pepsin breaks down the protein in the food into smaller particles, such as peptide fragments and amino acids.
