Question

Thromboxane A2 is: a) an oxygen-storage molecule inside platelets andphagocytes B) an enzyme that stimulates the activity of fibroblasts tohelp repair damage to blood vessel walls C) a prostaglandin in platelets that causes vasoconstrictionand platelet activation. D) a growth factor that stimuates the production ofplatelets E) a type of anticoagulant that blocks the action ofantithrobin III Thromboxane A2 is: a) an oxygen-storage molecule inside platelets andphagocytes B) an enzyme that stimulates the activity of fibroblasts tohelp repair damage to blood vessel walls C) a prostaglandin in platelets that causes vasoconstrictionand platelet activation. D) a growth factor that stimuates the production ofplatelets E) a type of anticoagulant that blocks the action ofantithrobin III

Explanation / Answer

      Thromboxane A2 is:       C) a prostaglandin inplatelets that causes vasoconstriction and plateletactivation       Thromboxane is representedas Tx, hence Thromboxane A2 is written as TxA2.       It is a product ofcyclooxygenase catalyzed metabolism of arachidonic acid.       It is formed viaprostaglandin enderoperoxide intermediate by a specificsynthase.       Hence we can say that itis a prostaglandinin in platelet.       TxA2 is amember of family of lipids known as eicosanoids.       The two major Thromboxanesare  TxA2 and  TxB2.        TxA2 is avasoconstrictor and apotent hypertensive agent that facilitates platelet aggregation.              Hope you are satisfiedwith the answer.        TxA2 is avasoconstrictor and apotent hypertensive agent that facilitates platelet aggregation.              Hope you are satisfiedwith the answer.
