Molly, a second year neuroscience graduate student, treats neurons grown in a petri dish with drugs that block the function of neuronal receptors. What is a consequence of the drug treatment?
 
  a. The neurons will become depolarized, initiating a refractory period.
  b. The neurons will become hyperpolarized and less likely to initiate another action potential.
  c. The synaptic vesicles will be void of neurotransmitters, blocking neuronal communication.
  d. Action potentials will fire immediately, enhancing neuronal communication.

Question 2

Synaptic vesicles have been released from their protein anchors. What happens next?
 
  a. The vesicles cross the synaptic gap, deliver their contents to the receptors, and dissolve into the fluid.
  b. The vesicles migrate to the cell membrane, spill their contents into the synaptic gap, and complete their life cycle.
  c. The vesicles cross the synaptic gap, enter the receiving neuron and deliver their contents to the receptors.
  d. The vesicles migrate to the cell membrane, spill their contents into the synaptic gap, and are refilled for later use.
