Question

Quizplus · Accepted Answer

Pepsin is an enzyme present in gastric juice that begins the digestion of protein. It breaks down long protein chains into smaller peptide chains. Water is a component of gastric juice but does not have any significant role in digesting protein. Trypsin is an enzyme produced in the pancreas and is involved in the digestion of proteins in the small intestine. Gastrin is a hormone that stimulates the secretion of gastric juice but is not directly involved in protein digestion.
