Final answer:
An anticoagulant inhibits the synthesis of factors II, VII, IX, protein C, and protein S, which are important for blood clotting.
Step-by-step explanation:
An anticoagulant is a substance that opposes the coagulation process. The anticoagulant mentioned in the question inhibits the synthesis of factors II, VII, IX, protein C, and protein S. These factors are important for blood clotting. When the synthesis of these factors is inhibited, the clotting process is reduced, which can help prevent the formation of blood clots.
