Energy and Cell Communication

Present in a target cell that receives the signal molecule

Membrane Receptors

3 Types of Membrane Receptors

Tyrosine Kinase Receptor

Promotes the growth and survival
of cells in animal cells

G-Protein Link Receptor

Convert extracellular signals into intracellular responses

Ion Channel Receptor

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

Hydrophilic is a polar, charged and/or large signal molecule

First Messenger

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

Second Messenger

Plasma Membrane

signal molecules are received at surface by membrane receptors

Intracellular Receptors

Cytoplasm

Receptors is inside the cell

Nucleus

Hydrophobic is a nonpolar signal molecule

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

Steroid Hormones

The Steroid hormone aldosterone passes through the plasma membrane

Aldosterone binds to a receptor protein in the cytoplasm activating it
