Compare and contrast receptor recognition between a hydrophobic and hydrophilic hormone
What will be an ideal response?
ANSWER: Hydrophobic hormones are typically lipid soluble hormones--steroids or fatty acid
derivatives. These will diffuse into the cell and bind to intracellular receptors. Typical
action of these hormones is to affect gene activity. Hydrophilic hormones are non-lipid
soluble and thus cannot easily enter the cell. Receptors are typically membrane bound. The
binding of the hormone to the receptor results in activation of a type of second messenger, which then causes a variety of effects from permeability changes to changes in enzyme
activity.
