Small molecular weight lipophilic hormones usually
A) Bind to surface molecules and act through G-protein coupled receptors
B) Bind to cytosolic or nuclear receptors and alter gene expression
C) Bind to catalytic receptors on the surfaces of cells
D) Directly activate channels on the surface membrane
E) Bind to surface molecules and act through the JAK-STAT pathway

Question

Quizplus · Accepted Answer

Small molecular weight lipophilic hormones, due to their ability to easily cross cell membranes, typically bind to cytosolic or nuclear receptors and alter gene expression. This is in contrast to hydrophilic hormones, which cannot easily cross the cell membrane and thus often bind to surface receptors.
