Meredith Villegas · Answer 1

Inhibition of platelet activation during blood clotting.

Explanation:

Epinephrine serves as one of the weak agonists for platelets. Binding of epinephrine to alpha-adrenergic receptors serves to stimulate the activation of platelets. It does not inhibit the platelet activation during clot formation. Being a weak agonist, epinephrine can stimulate the platelet activation directly but depends on strong agonists such as thrombin to initiate the process.
