A) act independently of their receptor proteins

C) open sodium channels
D) hyperpolarise the membrane

Question

Quizplus · Accepted Answer

Inhibitory neurotransmitters such as GABA and glycine function by binding to receptors on the postsynaptic neuron, causing an influx of negatively charged ions or an efflux of positively charged ions leading to a hyperpolarization of the membrane. This makes it more difficult for the neuron to fire an action potential and therefore inhibits neuronal activity.
