← Human Body & HealthIf a patient has a mutation that disables thromboxane production in platelets, which consequence follows during vascular injury?
A)Increased fibrinolysis immediately occurs
B)Platelet aggregation becomes significantly impaired✓
C)Prothrombin activation accelerates rapidly
D)Antithrombin activity becomes more effective
💡 Explanation
Thromboxane A2 (TXA2) is a key mediator for platelet aggregation because it promotes the activation of other platelets and increases their adherence to the injury site. Therefore, disabling its production impairs platelet aggregation, rather than accelerating other coagulation pathways.
