a. Estrogen is kept away from the surface of any cells not able to bind it at surface.
b. Estrogen has specific receptors inside several cell types, but each cell responds in the similar way to its binding.
c. estrogen has different shaped receptors for each of numerous cell types.
d. estrogen binds to exact receptors inside many kinds of cells, each of which have different responses to its binding.
e. estrogen is produced in extremely large concentration and then diffuses widely.
