Local signaling, one cell discharges molecules into the extracellular fluid around it.
Synaptic signaling

local signaling...nerve cell releases into the synapse (right by)
Hormonal Signaling

Long distance...hormone travels in bloodstream to target cells..all over body.
Reception

the cell's detection of a signaling molecule coming from outside the cell.
Transduction

the binding of the signaling molecule changes the receptor protein, this changes the signal to a form that can bring a cell response
Response

a specific cellular response for to a cell signal
Ligand

molecule that binds to another molecule, used in signaling
Protein Kinase

name for enzyme that transfers phosphate groups from ATP to a protein
Protein Phosphatases

enzymes that can rapidly remove phosphate groups from proteins
