Chapter 11.5, Problem 1QC
Summary Introduction
To review:
The two classes of neurotransmitter receptor.
Introduction:
The proteins that are present on the membrane of neuronal and glial cells andare activated by specific neurotransmitters are called neurotransmitter receptors. A neurotransmitter receptor binds with the neurotransmitter to transport the signal from one neuron to another.
