Gastric digestion takes place efficiently in
(a) acidic medium
(b) alkaline medium
(c) neutral medium
(d) highly alkaline medium


Correct Answer(a) acidic medium

Explanation:

The stomach wall or gastric glands secretes gastric juice containing three substances hydrochloric acid, mucus, and pepsin.

One of the functions of hydrochloric acid is to kill bacteria that may enter the stomach with food. The mucus protects the inside layer of the stomach from the damaging effect of the substance hydrochloric acid whereas the substance pepsin is an enzyme for digestion.  It helps in the digestion of proteins. The partially digested food then enters into the small intestine for further digestion.
