Question 1 Report

In the diagram above which shows the digestive tract for a certain farm animal, which of the following enzymes is not secreted by the part labelled III?

Answer Details
The part labelled III in the diagram refers to the small intestine, which is responsible for the majority of nutrient absorption. The small intestine produces several enzymes to help digest food, including amylase, lipase, and trypsin. Pepsin is not produced in the small intestine (part III). Pepsin is actually produced in the stomach (part II) and is responsible for breaking down proteins into smaller peptides. Once the food is mixed with gastric juices in the stomach, it enters the small intestine where other enzymes take over the process of digestion and absorption of nutrients. Therefore, the correct answer is Pepsin.
