Question

Why digestion of proteins in stomach is not possible in the 1
absence of HC1?
​

Answer 1

Hydrochloric acid is necessary to make the medium acidic which allows inactive enzyme pepsinogen to be converted into pepsin. Pepsin plays an important role in the digestion of proteins.

Answer 2

Answer:

Food digestion is the breakdown of large food particles into smaller absorbable nutrients needed for energy production, growth, and cellular repair. It begins with ingestion and ends with defecation. Digestion takes place in the gastrointestinal tract in two principal forms: mechanical and chemical. Mechanical digestion is the physical degradation of large food particles into smaller pieces that digestive enzymes can access through chemical digestion.
