{} do not pass easily through cell membranes stored in membrane-bound vesicles soluble in blood for transport . cell-surfacereceptors Lipid-soluble (lipophilic) . pass easily through membranes . not stored in membrane-bound vesicles . require binding proteins for transport . cytoqolic or nuclear receptors '@fvlk , 10. What does all this mean for the use of hormones? Very.different from nervous system: Nervous transmissions more of a cell to cell signal. Hormones are broadcast: efficient to get to many places. One hormone (one more easily produced/ less complicated to control than lots of different chemicals) can do lots of things. Cells themselves determine if they respond. Long-lasting effect: 1) hormone may not be degraded right away, 2)
