Detailed explanation-1: -Pepsin is a stomach enzyme that serves to digest proteins found in ingested food. Gastric chief cells secrete pepsin as an inactive zymogen called pepsinogen. Parietal cells within the stomach lining secrete hydrochloric acid that lowers the pH of the stomach. A low pH (1.5 to 2) activates pepsin.
Detailed explanation-2: -Abstract. 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.
Detailed explanation-3: -Enzymes that are secreted in stomach will show maximum activity in acidic pH. Out of the given options only pepsin is an enzyme secreted in stomach.
Detailed explanation-4: -Pepsin is an enzyme that works at an optimal pH of 2.
