Which would be more likely to carry out endocytosis: a white blood cell engulfing foreign materials or a cell that excretes hormones? Explain

A white blood cell engulfing foreign materials is more likely to carry out Endocytosis.

Explanation:

Endocytosis is the process by which a cell takes up a macromolecule into is cytoplasm by forming a vessicle. In the question two cases are given, both the cases involve the formation of membrane bound vessicle but in different ways. The excretion of hormones involves the movement of molecule outside the cytoplasm. This process is exocytosis. The engulfment of an antigen by WBC involves taking up of molecule within the cell so that it can be killed and digested. Thus in this case Endocytosis is more likely to occur ...
