Answer to Question 1

ANS: B
Fibrinogen binds to the receptor GP IIb/IIIa. Membrane phospholipids supply arachidonic acid, which becomes converted to thromboxane during platelet activation. They form part of the platelet glycocalyx, which is the platelet surface. Many of the coagulation enzymes bind to platelet phospholipids, including factor IX, X, and prothrombin.

Answer to Question 2

ANS: A
Fibrinogen must bind to its receptor GP IIb/IIIa assembled on the platelet membrane after activation for normal platelet aggregation.
