Answer to Question 1

ANS: B
Heparin binds to antithrombin, thus bringing thrombin in close proximity to antithrombin. It also changes the configuration of antithrombin so that it can effectively bind thrombin. The thrombin-antithrombin complex renders thrombin inactive; the complex is taken to the liver and cleared.

Answer to Question 2

ANS: D
Thrombin binds the endothelial cell membrane protein thrombomodulin, and the complex then activates protein C. Activated protein C complexes with protein S, and the complex degrades factors Va and VIIIa, which downregulates thrombin generation.
