Hydrochloric acid is secreted by the cells lining the – (1) Oral cavity (2) Stomach (3) Ileum (4) Colon
by

1 Answer

Answer :

(2) Stomach Explanation: The chief cells of the stomach secrete enzymes for protein breakdown (inactive pepsinogen and rennin). Hydrochloric acid activates pepsinogen into the enzyme pepsin, which then helps digestion by breaking the bonds linking amino acids, a process known as proteolysis.
