What is an enzyme-linked receptor? the receptor is also an enzyme
signal binging actiate the catalytic domain
ex. insulin receptor in skeletal muscle linked to
tyrosine kinase
What is the first messenger? the ligand that binds to a G-protein coupled
receptor
can be a neurotransmitter, hormone, or drug
How does the G-protein coupled alpha dissociates from beta and gamma
receptor activate the effector?
After an effector activates the 2nd messenger starts an enzymatic cascade to
second messenger, what is the next lead to a cellular response
step?
The intracellular response to the 2nd tissue specific
messenger is _________________
