Question

Quizplus · Accepted Answer

Lipid-soluble signaling molecules like aldosterone can cross cell membranes, but they only affect target cells because the intracellular receptors that bind to these molecules are present only in target cells. This allows the signaling molecule to initiate a response in the target cell while leaving non-target cells unaffected.
