Question

Quizplus · Accepted Answer

The membrane attack complex (MAC) functions by creating pores in the plasma membrane of target cells, such as bacteria. This action allows water and ions, including sodium, to rush into the cell, leading to osmotic swelling and eventually cell lysis or death. This mechanism is part of the immune system's defense against pathogens.
