Analyzing the Statement

1. Understanding Warfarin's Mechanism:

   • Warfarin is a medication commonly used as an anticoagulant to prevent blood clots.
   • It functions by inhibiting the enzyme epoxide reductase, which is responsible for the conversion of vitamin K to its active form.

2. Vitamin K Role:

   • Vitamin K is essential for the synthesis of certain clotting factors in the liver, which are necessary for normal blood coagulation.

3. Blockage of Vitamin K Activation:

   • By blocking the activation of vitamin K, warfarin decreases the production of these clotting factors, thus exerting its anticoagulant effect.

Conclusion

Based on the understanding of warfarin's mechanism and its effect on vitamin K:

Final Answer

True. Warfarin indeed acts by blocking the enzyme that activates vitamin K.
