In what part of the cell does a polar signaling molecule bind its receptor? A nonpolar signaling

molecule? Explain your reasoning. What will be an ideal response?


Polar signaling molecules bind membrane receptors whereas nonpolar bind cytpplasmic
receptors.Polar slgnaling molecules are hydrophilic and cannot cross the plasma membrane. Nonpolar
signal molecules are hydrophobic and able to cross the plasma membrane to bind a cytoplasmic
receptor.
