Good, that's right.

What happens when C7 joins the C5bC6 complex ?

• The complex breaks down to form C8

• The complex undergoes a structural change, becoming more hydrophilic and allowing it to dissolve

• The complex undergoes a structural change, becoming more acidic and allowing it to be cleaved

• The complex undergoes a structural change, becoming more hydrophobic and allowing it to bind to membranes
