Question: 1 / 400

Heparin works by binding to which substance?

Antithrombin III

Heparin works by binding to Antithrombin III, a protein that inactivates various clotting factors in the blood. This helps to prevent the clotting process and keep the blood flowing smoothly throughout the body. Option B, Activated factor X, is a clotting factor that heparin helps to inactivate. Vitamin K (option C) is not a protein and does not have a direct role in the clotting process. Immunoglobulin IgE (option D) is an antibody involved in allergic reactions, and it does not play a role in the clotting process. Therefore, options B, C, and D are incorrect.
