Detailed explanation-1: -For proteins, it is the enzyme pepsin that digests them. Pepsin is secreted by the stomach chief cells in the stomach along with hydrochloric acid. Thus, protein digestion occurs in the stomach of the human digestive tract. Proteins are the most complex molecules and undergo further digestion in the small intestine.

Detailed explanation-2: -Proteins are first digested in the stomach by the action of pepsin which is secreted by peptic or chief cells as proenzyme pepsinogen and it converts proteins into smaller polypeptides.

Detailed explanation-3: -From the Stomach to the Small Intestine The stomach empties the chyme containing the broken down egg pieces into the small intestine, where the majority of protein digestion occurs.
