Which of the following is/ are brush border enzyme(s)?

a) Amylase

b) Carboxypeptidase

c) Aminopeptidase

d) a., b., and c.

e) Both a. and c., but not b.

Solution

C) C. Aminopeptidases
Brush border cells are the cells present in the small intestine which present in the small intestine. These are finger like projections on the surafec of epithelial cells, also known as microvili. The vili and microvili increase the surface area of the intestine. These produce aminopeptidases.

*Carboxypeptidases are produced by pancreatic acinar cells and amylases are produced by salivary glands (salivary amylases) and pancreatic acinar cells (pancreatic amylases).
