Question

Name the first digestive organ that is associated with the breakdown of proteins in humans.

Answer 1

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

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.
