Southern Copperhead Snake Venom Contains a Protein Called Disintegrin

Southern Copperhead snake venom contains a protein called disintegrin. Disintegrins bind to a class of membrane receptors called integrins. Platelets use integrin receptors to aggregate at a site of tissue damage. Why does the snake venom contain this molecule?

A) After the snake bites its prey, the molecule helps in wound healing.
B) The molecule helps kill the snake's prey by producing large clots that travel in the body and produce heart attacks and strokes.
C) By binding to the platelets, the molecule inhibits the formation of fibrin.
D) The molecule interferes with clot formation so that the venom can travel more efficiently from the site of the bite to the rest of the body.
