Verified step by step guidance

Understand the role of the complement system in the immune response. The complement system is a part of the immune system that enhances the ability of antibodies and phagocytic cells to clear microbes and damaged cells.

Learn about the Membrane Attack Complex (MAC). The MAC is a structure formed on the surface of pathogen cell membranes as a result of the activation of the complement system.

Recognize that the MAC is responsible for cell lysis. It forms a pore in the membrane of the target cell, leading to an influx of water and ions, which causes the cell to swell and burst.

Differentiate between the MAC and other complexes like Prostaglandin, Leukotriene, and Histamine complexes, which are involved in different physiological processes such as inflammation and allergic responses.

Conclude that the Membrane Attack Complex is the correct answer as it directly leads to cell lysis through the formation of pores in the cell membrane.
