Question

the enzyme that breaks down protein is:
a lipase
b lactase
c amylase
d pepsin
e bile
question 38
which of the following is not an accessory organ to the small intestine?
a pancreas
b liver
c duodenum
d gallbladder

Explanation:

For the first question: Lipase breaks down lipids, lactase breaks down lactose (a sugar), amylase breaks down starch (a carbohydrate), bile is not an enzyme (it emulsifies fats), and pepsin is a protease that breaks down proteins in the stomach.
For the second question: Accessory organs of the small intestine aid digestion but are not part of the intestinal tract. The pancreas, liver, and gallbladder are accessory organs; the duodenum is the first section of the small intestine itself (a primary organ, not accessory).

Answer:

D. Pepsin
C. duodenum
