Ligand gated channel receptors
signal molecule binds as a ligand to the protein receptor, which either opens or closes the gate
-very important in the nervous system
G-Protein linked receptors
-works as molecular switch, if GDP is attatched, switch is off, but if GTP is attatched, switch is on
-signal moelcule binds to extracellular part of receptor, which activates receptor, then binds to inactive side of G-protein, making GTP replace GDP
Tyrosine Kinase
-first individual polypeptides, then bind and become dimers: activae each other, adds phosphate from an ATP molecule on tail of other polypeptide
-relay proteins recognize receptor proteins, changes structure of protein, leads to cellular response
What are the 3 steps in cell signaling?
1) Reception
2) Transduction
3) Response
What are second messengers?
-small,nonprotein, water-soluble ions that spread throughout cell by diffusion
