Answer #1

Answer :-. it is necessary for the activation of gastric enzymes produced by chief cells...

Explanation =gastric juice includes hydrochloric acid, Pepsinogen, Mucus, Intrinsic Factor and each chemical has specific function..... For example

Function: Hydrochloric Acid

Superior solvent of 0.8 acidity (pH)

Function: Pepsinogen- a protein

Converted into an enzyme (pepsin) with the action of HCL. Pepsin begins a chemical breakdown.

Function: Mucus

thick protective coat for stomach lining

Function: Intrinsic factor

protein that binds to vitamin B12, and enables the absorption of vitamin B12

Thanks dear student
