[pane00]

Inactivation of a transporter in the presynaptic membrane would be expected to
 
  a. increase the levels of the transmitter in the synapse.
  b. increase synthesis of the transmitter.
  c. increase reuptake of the transmitter.
  d. provide negative feedback on synthesis or release of transmitter.
  e. increase the transmitter synthesis.

Question 2

Activation of a presynaptic autoreceptor on dendrites can produce a hyperpolarization that
 
  a. releases more transmitter.
  b. increases synthesis of transmitter.
  c. increases reuptake of the transmitter.
  d. reduces transmitter release by reducing the axon firing rate.
  e. increases the number of receptors at the synapse.
