Question

"A white blood cell is capable of producing and releasing thousands of antibody molecules every second. Antibodies are large, complex protein molecules. How would you expect them to leave the cell?

A. Exocytosis
B. Receptor mediated endocytosis
C. Pinocytosis
D. Passive transport"

Answer 1

Antibodies produced by white blood cells are released from the cell through exocytosis.

Step-by-step explanation:

The antibodies produced by white blood cells are large, complex protein molecules. To leave the cell, the antibodies are transported through a process called exocytosis. In exocytosis, the cell membrane fuses with vesicles containing the antibodies, and the vesicles release their contents to the outside of the cell.

This allows the antibodies to be released and perform their function in defending against pathogens.
