Question

Which of the following is an effect of opsonization?A) increased adherence of phagocytes to microorganismsB) increased margination of phagocytesC) increased diapedesis of phagocytesD) inflammationE) cytolysis

Answer 1

Answer: A) increased adherence of phagocytes to microorganisms

Explanation:

The phenomenon of phagocytosis can be facilitated by certain substances called opsonins. Particles coated by antibodies or by certain products of the activation complement system adhere to the phagocyte membrane and are internalized more rapidly and intensely than those that are not opsonized. In the macrophage membrane, there are surface molecules, known as receptors, that have an affinity for these opsonins.
