Question

in which of the following methods of secretion are the secretory products enclosed in vesicles released from the apical surface of the cell by exocytosis?
a.) endocrine secretion
b.) merocrine secretion
c.) holocrine secretion
d.) apocrine secretion

Explanation:

Merocrine secretion (also called eccrine secretion) is a method where secretory products are enclosed in vesicles and released from the apical surface of the cell by exocytosis. Endocrine secretion releases hormones into the bloodstream. Holocrine secretion involves the rupture of the cell to release secretions. Apocrine secretion involves budding off of membrane - bound vesicles from the cell.

Answer:

B. Merocrine secretion
