When light strikes a molecule of photopigment, the membrane potential undergoes a(n) ________, which in turn ________.
 
  a. action potential; releases an excitatory transmitter onto the ganglion cell
  b. hyperpolarization; reduces release of an inhibitory transmitter onto the bipolar cell
  c. depolarization; releases an excitatory transmitter onto the ganglion cell
  d. action potential; releases an inhibitory transmitter onto the ganglion cell
  e. hyperpolarization; increases the release of an inhibitory transmitter onto the bipolar cell

Question 2

Which of the following is true of the visual transduction process?
 
  a. In the dark, the photoreceptor releases a transmitter that inhibits the bipolar cell.
  b. Light depolarizes the photoreceptor.
  c. Action potentials are recorded from the bipolar cell after light exposure.
  d. Action potentials are recorded from the photoreceptors after light exposure.
  e. In the dark, the photoreceptor releases a transmitter that excites the bipolar cell.
