According to Figure 9.6, what is a key difference between cell signaling by a cell-surface receptor and cell signaling by an intracellular receptor?

A)Cell-surface receptors bind to specific signaling molecules; intracellular receptors bind any signaling molecule.
B)Cell-surface receptors typically bind to signaling molecules that are smaller than those bound by intracellular receptors.
C)Cell-surface receptors bind polar signaling molecules; intracellular receptors bind nonpolar signaling molecules.
D)Signaling molecules that bind to cell-surface receptors lead to cellular responses restricted to the cytoplasm; signaling molecules that bind to intracellular receptors lead to cellular responses restricted to the nucleus.
E)None of the other answer options is correct.
