signal transduction
DEFINITION 1

that occur inside the cell
TERM 2
GPCR
DEFINITION 2
G protein couled receptor
TERM 3
G protein-coupled receptor
DEFINITION 3
a group of related receptors that span the plasma membrane
seven times. the binding of this ligand to its specific receptor
causes a chang in the conformation of the receptor tha
increases it afinity for a heterotrimic G protein initiating a
response within the cell.
