Question

_____ and _____ are common neurotransmitters that elicit IPSPs and are therefore called inhibitory neurotransmitters.

Answer 1

GABA and glycine are common inhibitory neurotransmitters that create IPSPs by causing hyperpolarization of the postsynaptic membrane, thus making neurons less likely to fire action potentials.

Step-by-step explanation:

Two common neurotransmitters that elicit inhibitory postsynaptic potentials (IPSPs) and are therefore called inhibitory neurotransmitters are gamma-aminobutyric acid (GABA) and glycine. When GABA is released from a presynaptic neuron, it binds to and opens Cl- channels, allowing Cl- ions to enter the cell. This causes hyperpolarization of the postsynaptic membrane, making the neuron less likely to fire an action potential. Similarly, glycine acts as an inhibitory neurotransmitter by causing hyperpolarization upon its receptor's activation.
