There are two receptors that neurotransmitters interact with: ligand-gated receptors or ionotropic receptors and G protein-coupled receptors or metabotropic receptors depending on the neurotransmitter (the ligand). When the ligand binds with the neurotransmitter receptor it causes a sequence of chemical reactions to relay signals.

What else can I help you with?
What does an axon release when an impulse reaches the end of it?
Neurotransmitters to the synapse and the neurotransmitters bind with the receptors releasing the second messengers.
Which of these neurotransmitters does not bind to a plasma membrane receptor?
Nitric oxide does not bind to a plasma membrane receptor.
Chemicals that cross the synaptic gap and bind to receptors on another neuron are called?
nuerotransmitter
What are characteristics of neurotransmitters?
Neurotransmitters are released in response to stimulation. They alter the physiology of the postsynaptic cell. They are synthesized by a presynaptic neuron. They bind to specific receptors on the postsynaptic cell.
Where are neurotransmitters released?
Neurotransmitters are released from the axon terminal of a neuron into the synaptic cleft, which is the small gap between the axon terminal and the dendrite of a neighboring neuron. neurotransmitters then bind to receptors on the receiving neuron, transmitting the signal.
Neurotransmitters bind to specific proteins on the postsynaptic membrane called?
Neurotransmitters bind to specific proteins on the postsynaptic membrane called receptors. These receptors initiate a series of events that can either excite or inhibit the firing of the postsynaptic neuron.
Where do neurotransmitters that bind the postsynaptic membrane generate?
Neurotransmitters that bind to the postsynaptic membrane generate a response by either depolarizing or hyperpolarizing the postsynaptic neuron. This response can lead to the generation of an action potential if the threshold is reached, propagating the signal further along the neuron.
Do neurotransmitters pass directly from the axon to the dendrite?
No, neurotransmitters are released from the axon terminal into the synaptic cleft between the axon terminal and the dendrite. They then bind to receptor sites on the dendrite to transmit signals from one neuron to another.
Are neurotransmitters sometimes referred to as a key?
Yes, neurotransmitters are sometimes referred to as "keys" because they play a critical role in transmitting signals between nerve cells, or neurons. These molecules bind to specific receptors on the surface of neurons, which triggers a response in the receiving cell. Just like a key fits into a lock to open a door, neurotransmitters bind to receptors to either excite or inhibit activity in the brain and body.
Neurotransmitters attach to what molecules in the cell membrane?
Neurotransmitters attach to specific proteins called receptors on the cell membrane. These receptors are typically ligand-gated ion channels or G protein-coupled receptors that initiate cellular responses when neurotransmitters bind to them.
What are direct acting neurotransmitters?
Direct acting neurotransmitters are neurotransmitters that directly bind to and activate ionotropic receptors on the postsynaptic neuron, causing a rapid change in membrane potential and leading to a quick response. Examples include acetylcholine and certain amino acids like glutamate and GABA.
Where do neurotransmitters go when they reach the end of a neuron?
Neurotransmitters are released into the synaptic cleft when they reach the end of a neuron. From there, they bind to receptors on the postsynaptic neuron, initiating a new electrical signal to continue the communication process. Some neurotransmitters may be recycled back into the presynaptic neuron or broken down by enzymes.
