Q.10:- What would happen if HCl were not secreted in the stomach?
If HCl were not secreted in the stomach then it would affect protein digestion. The HCl secreted by glands present on stomach walls provides acidic medium to food. The acidic medium allows pepsinogen to be converted into pepsin. Pepsin plays an important role in the digestion of proteins. Therefore, if HCl were not secreted in the stomach, then pepsin would not be activated and affects its digestion.
