Figure 2. Efficacy curve of drugs A - E. Determine if the following statements (Q16-21) are (A) TRUE or 16. Drug A is an agonist 17. Drug C is an antagonist? 18. Which of the above is a partial agonist? 19. The EC50 of drug B is less than O.01 ng/ml d. All of the above (B) FALSE. 50 .001 0.01 0.1 1 10 100 [Drugl (ing/ml) ning Drug A and drug D will lad to a response that is greater than both drugs singly 21. Combining Drug A with increasing doses of drug E will lead to a new curve that is to the right of 20.

Explanation / Answer

16-True [Any medication/chemical molecule that binds a receptor and yields a consequence.]

17- True [Any medication/chemical molecule that lumps the consequence of an agonist.]

18-Drug C [Any medication/chemical molecule that lumps the consequence of an agonist.]

19-True [Greatest consequence of the medication, this is an pointer of efficiency]

20-False [drug absorption obligatory to bind 50% of the receptor locations in the system.]

21-False [Medications with an advanced affinity are typically extra potent. The reduced the Kd, the superior the affinity]
