Describe the nature and location of intracellular receptors for hormones that pass easily through cell membranes. Explain how their role compares to the signal-transduction pathway notes above, and describe the changes they are likely to trigger within the target cell.

Hormones that pass easily through the cell membrane are lipid soluble hormones. Receptors for these types of hormones are located within the cell; therefore, these hormones pass through the plasma membrane of cell in order to bind to these receptors. On the other hand, signal transduction pathways bind to receptors located on the plasma membrane in order to activate these types of reactions
