Question

Quizplus · Accepted Answer

Neural peptides are special neurotransmitters that can directly control the release of other neurotransmitters. They are larger than typical neurotransmitters and are made up of chains of amino acids. When they are released into the synapse, they can bind to specific receptors on the presynaptic neuron and modulate the release of other neurotransmitters. Examples of neural peptides include substance P and enkephalins.
