Lipid-soluble signaling molecules, such as aldosterone, cross the membranes of all cells but affect only target cells because

  1. A.    only target cells retain the appropriate DNA segments.
  2. B.     intracellular receptors are present only in target cells.
  3. C.     only target cells have enzymes that break down aldosterone.
  4. D.    only in target cells is aldosterone able to initiate the phosphorylation cascade that turns genes on.

A cell has epinephrine receptors, yet is unable to respond to epinephrine signaling.  One possible reason is:     A. The cell has no DNA.     B. The cell is missing a functional G-protein or adenylyl cyclase.         C. All of the epinephrine receptors are on the cell’s surface. (They’re supposed to be in the cytoplasm!)       D. Both A and C.
EGF signals by binding to cell surface EGF receptors. Which of these observations, if true, would BEST explain EGF’s mechanism of action? A.

EGF is hydrophilic and cannot diffuse through the cell membrane D. EGF is hydrophobic and cannot diffuse through the cell membrane
