Question 2

Given the characteristics of small-molecule transmitters and neuropeptides, we can conclude that small-molecule transmitters
 
  a. are well-suited to roles as neurotransmitters, whereas neuropeptides are well-suited to roles as neuromodulators.
  b. are well-suited to roles as neuromodulators, whereas neuropeptides are well-suited to roles as neurotransmitters.
  c. and neuropeptides are equally well-suited to be either neurotransmitters or neuromodulators.
 d. and neuropeptides frequently act as neuromodulators and neurohormones, but rarely function as neurotransmitters.
