Small-molecule neurochemicals and neuropeptides are used by neurons in synaptic communication. But beyond the commonality of both being used in synaptic communication, there are substantial differences in how they are used. Compare the mechanism of action and inactivation for small-molecule neurochemicals and neuropeptides, discussing duration of effect, inactivation, and other differences in these mechanisms.
What will be an ideal response?
Small molecule neurochemicals are faster to act and faster to be inactivated or removed than neuropeptides. While small molecule neurochemicals are used for rapid synaptic communication, neuropeptides are used for modulating synaptic communication for longer periods of time.
