<span> Gastrin is produced by
G cells in the pylorus and the duodenum. Gastrin stimulates the secretion of
both parietal and chief cells. It causes the gastric glands to increase their
secretory activity and stimulates gastric motility. Saliva, food, and gastric
juice are mixed together in the stomach to form chyme. The stomach serves as a
reservoir for food before release into small intestine. Gastric juice is
secreted into the lumen of the stomach. Gastrin is secreted into the
bloodstream.</span>
Answer:
The correct answer is "pepsin".
Explanation:
Pepsin is an enzyme that catalyzes the hydrolysis of proteins, breaking it down into its subunits called amino acids. Pepsin is an important component of the gastric juice because it contributes largely to proteins digestion. In this case, James is having trouble to digest lean steaks and other protein-rich foods. This problem indicates that James is likely lacking the enzyme pepsin.
