Detailed explanation-2: -Normal Results The normal volume of the stomach fluid is 20 to 100 mL and the pH is acidic (1.5 to 3.5).
Detailed explanation-3: -Pepsin is an aspartic protease that acts in food digestion in the mammal stomach. An optimal pH of around 2 allows pepsin to operate in its natural acidic environment, while at neutral pH the protein is denatured.
