Question

Quizplus · Accepted Answer

Enterokinase is an enzyme secreted by the small intestine that activates trypsinogen into trypsin, making option E the correct match.

Answer: A 
 Bile salts are secreted by the liver and stored in the gallbladder, and are not enzymes that are activated by enterokinase. It is used to emulsify fats in the small intestine, so they can be digested by lipase. Therefore, option A is not the correct match.

Answer: B 
 Pepsinogen is an inactive precursor of pepsin, which is activated by the acidic environment in the stomach. Therefore, option B is not the correct match.

Answer: C 
 Amylase is an enzyme that breaks down carbohydrates and is secreted by both the pancreas and salivary glands. It requires no activation by enterokinase, making option C not the correct match.

Answer: D 
 Lipase is an enzyme that breaks down fats and is secreted by the pancreas. It requires no activation by enterokinase, making option D not the correct match.
