The cells performs exocytosis because it must remove the pathogen.
Based on the situation, one can infer that the receptors are antigens that are specific in their function.
I hope I helped! :)
Answer:
The correct answers are endocytosis and the receptors are specific for the cells.
Explanation:
The white blood cells are the unique cells of the immune system. They perform an essential function of safeguarding the body from foreign agents like bacteria. In order to do so, they identify the bacteria and produces an envelope around it, pinching off the vacuole. With the help of this, the cell performs a procedure known as endocytosis.
On the white blood cells, the receptors found are very unique, as because of them they identify the particular foreign particles, like B cells generate antibodies that combines with the particular antigens, and thus, impart specific immune response. Or it can be said, that specific foreign component is identified by the unique white blood cell, which shows that the receptors on these cells are unique.
