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.

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.
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 receptors. These receptors initiate a series of events that can either excite or inhibit the firing of the postsynaptic neuron.
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.
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.
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 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.
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.
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.
