Final answer:
GABA and glycine are examples of inhibitory neurotransmitters. They bind to and open Cl- channels, resulting in hyperpolarization and inhibition of the postsynaptic neuron.
Step-by-step explanation:
GABA (gamma-aminobutyric acid) and glycine are examples of inhibitory neurotransmitters. When GABA is released from a presynaptic neuron, it binds to and opens Cl- channels, resulting in the entry of Cl- ions and hyperpolarization of the postsynaptic membrane. This makes the neuron less likely to fire an action potential. Similarly, glycine also opens Cl- channels, leading to hyperpolarization and inhibition of the postsynaptic neuron.
