The larger the dissociation constant K_Dis, the smaller will be A) the rate at which a ligand dissociates from its receptors. B) the affinity of the receptor for its ligand. C) the effect of a ligand on a signal transduction pathway. D) the number of ligand molecules needed to stimulate a signal transduction pathway. E) the number of cell surface receptors that bind a ligand.

Question

Quizplus · Accepted Answer

The dissociation constant (K_D_/) represents the affinity of the receptor for its ligand. A larger dissociation constant means that the affinity of the receptor for its ligand is smaller. Therefore, option B is the best choice. Options A, C, D, and E do not directly relate to the dissociation constant.

The Larger the Dissociation Constant KD is, the Smaller Will
