Just wondering what equation to use to work about a and c? 3. A competitive antagonist of the CB1 receptor, SR141716A, has an equilibrium binding affinity constant (KN) for the CB1 receptor of approximately 5.6 x 109 M-1. (This is the information from the question prior: THC binds to the CB1 cannabinoid receptor and causes receptor activation, leading to a range of intracellular signals through an array of G proteins. THC binds to CB1 with a dissociation constant (Kd) of...

Question 1 (1 point) Vasoconstriction occurs when epinephrine (adrenaline) binds to the a-adrenergic receptor on vascular smooth muscle cells. One way to treat high blood pressure is to administer competitive inhibitors that bind to this receptor. The Kd for binding of epinephrine to this receptor is ~UM. Based on the measured affinity (Kd) of the following drugs for the a-adrenergic receptor, which might be good candidates for high blood pressure medication? Drug A: Kd = 0.6 M; Drug B: Kd...
