Diamond yellow = dopamine, Blue = dopamine receptor, red uptake pump removes, Endorphin = works as neuromodulator, efftects signal within postsynaptic cell
Morphine binds to G prot receptor shape change interacts w/ G protein expels its GDP molecule and picks up GTP G protein breaks in two pieces here ½ binds to adenylyl cyclase and inhibits formation of Other times activated G prot change activity of ion channel/enzyme GTP breaks down GDP returns to resting conformation
Dopamine = BLUE, dopamine receptors = purple
Binding of opiates inhibits GABA release decreased inhibition of dopaminergic neurons more dopamine HIGH At mu receptor, acts as stronger agonist
Red = reward pathway, green = areas where opiates bind
