Question 65
H

In a person with cystic fibrosis, thick mucus can block the tube that carries enzymes from the pancreas to the small intestine. The pancreas still makes amylase, protease and lipase, but very little of these enzymes reaches the small intestine.

a.

Suggest why a person whose pancreatic tube is blocked may find it difficult to gain body mass.

[3]
b.

Some people with cystic fibrosis take capsules containing amylase, protease and lipase with each meal. The capsules have a coating that does not dissolve in acid.

Suggest why the coating must not dissolve in the stomach.

[2]
c.

Explain why a capsule that contained only protease would not solve the problem.
