oIf you have a very hydrophobic hormone, typically these
hormones can pass through the membrane if they are small
Ligand: chemical message that gets received on the receptor of another
cell type
%
Receptors: found in cell membrane or in cytosol
&

Binding of a hormone changes that receptor’s shape (conformational
change) and this causes it to be activated and information to be relayed
(
signal receptors that bind to steroid
hormones are located inside the cell
