C) The EC50 of venlafaxine for serotonin reuptake protein is lower than the EC50 for norepinephrine reuptake transporter.
D) The EC50 of venlafaxine for the norepinephrine reuptake transporter is lower than the EC50 for the serotonin reuptake transporter.
E) The EC50 of venlafaxine for the normal reuptake transporter is lower than the EC50 for the serotonin reuptake transporter.
