It secretes the following-

1. Pepsin- Breaks the proteins into peptides.

2. HCl- Makes the stomach acidic for pepsin to act on it

3. Mucus- Prevent the inner lining of stomach from coming in contact with the acid

Answer 2

First digestive organ associated with the breakdown of proteins in humans is Stomach.  

The Stomach Secretes -

1. Pepsin
2. Hydrochloric Acid (HCL)
3. Lipase

Explanation:

• After reaching the stomach, food is thoroughly mixed with gastric juices due to churning movements of the stomach.

• Gastric juice is secreted in the stomach which contains protein digesting enzyme pepsin.

• HCL is also secreted in the stomach in the presence of which pepsin gets activated and breaks proteins into amino acids.

• Pepsin is a stomach enzyme that serves to digest proteins found in ingested food. Gastric chief cells secrete pepsin as an inactive zymogen called pepsinogen.

• Lipase is a type of protein made by your pancreas, an organ located near your stomach. Lipase helps your body digest fats. It's normal to have a small amount of lipase in your blood.
