The interaction seen in the image is between a complement protein (C5b) and an inserted protein (MACPF) on a microbial cell membrane, leading to the formation of the membrane attack complex (MAC). The MAC creates pores in the microbial cell membrane, leading to its rupture and ultimately cell death. Therefore, the consequence of this interaction is the rupture of a microbial cell.
