In the Activation of Clotting Factors

In the activation of clotting factors

A) endothelial cells provide the phospholipid component in the intrinsic pathway of coagulation.
B) prothrombin molecules do not bind to phospholipids in the clotting activation process.
C) roughly, equal concentrations of plasma clotting factors participate in the coagulation cascade mechanism.
D) contact with a glass surface activates prothrombin (factor II) .
E) usually, during activation of clotting factors, a one-chain molecule is cleaved into a two-chain molecule with the chains held together by S-S bonds.
