The Steroid hormone aldosterone passes through the plasma membrane

Aldosterone binds to a receptor protein in the cytoplasm activating it

Diffuse directly across the lipid bilayer of the plasma membrane to encounter its receptor in the cytoplasm

Receptors is inside the cell

signal molecules are received at surface by membrane receptors

Diffuse through the plasma membrane. It's receptor is embedded in the membrane

First Messenger

Ion Channel Receptor

Allows direct conversion of a chemical neurotransmitter message to an electrical current.

G-Protein Link Receptor

Convert extracellular signals into intracellular responses

Tyrosine Kinase Receptor

Promotes the growth and survival of cells in animal cells
