<prompt> A paial agonist can antagonize the effects of a full agonist because it hasHigh affinity but low intrinsic activityLow affinity but high intrinsic activityNo affinity and low intrinsic activityHigh affinity but no intrinsic activity  <response>: High affinity but low intrinsic activity. The activity is mainly governed by affinity , intrinsic activity of a drug. iagonist has high affinity and intrinsic activity,antagonist has affinity but no intrinsic activity zero. Paial agonist has high affinity and low intrinsic activity. KDT 6e pg 37
