Two receptors,A and B,can bind the same chemical signaling molecules but the concentration of those molecules required to reach 50% saturation is twice as great for receptor B.Therefore,the receptors have the same ________,but different ________.
A)specificity;affinity
B)specificity;saturation
C)affinity;specificity
D)affinity;competition
E)competition;affinity
