most common cellular response to a signal

• turn genes on and off

• alter pemeability

• trigger an enzyme

receptors must

• conform to the shape of the ligand

• amplify messages

• turn genes on and off

a series of steps triggered by the receptor binding

• reception

• response

• signal transduction

• amplification

long distance signaling

• direct contact
