1. Identify the signal amplification steps in G-protein signal transduction pathways. Label the steps signal transduction and indicate on the bottom which steps are amplified. 2. Distinguish between the effector pathways associated with G-protein coupled receptors. a. Draw the effector pathway (horizontally) associated with the B-adrenergic receptor when it binds to Norepinephrine. Label the neurotransmitter, receptor, G-protein (type), Effector protein, second messengers, late effectors, and briefly describe its target actice.b. Draw the effector pathway (horizontally) associated with the Dopamine D2 receptor when it binds to Dopamine. Label the neurotransmitter, receptor, G-protein (type), Effector protein, second messengers, late effectors, and briefly describe its target action. c. Draw the effector pathway (horizontally) associated with the Glutamate receptor when it binds to Glutamate. Label the neurotransmitter, receptor, G-protein (type), Effector protein, second messengers, late effectors, and briefly describe its target action..
