chemically gated channels
The transport mechanism for a neurotransmitter across the synaptic cleft is called exocytosis. During exocytosis, neurotransmitter-filled vesicles fuse with the presynaptic membrane, releasing the neurotransmitter into the synaptic cleft where it can then bind to receptors on the postsynaptic membrane.
Synaptic vesicles primarily store neurotransmitters such as acetylcholine, dopamine, serotonin, norepinephrine, and gamma-aminobutyric acid (GABA). These chemical messengers are released into the synaptic cleft during neurotransmission, facilitating communication between neurons. The specific neurotransmitter stored in a vesicle depends on the type of neuron and its function within the nervous system.
Several factors can increase synaptic transmission, including the availability of neurotransmitters, the sensitivity of receptors on the postsynaptic neuron, and the frequency of action potentials in the presynaptic neuron. Enhanced calcium ion influx during action potentials also promotes neurotransmitter release. Additionally, the presence of neuromodulators, such as serotonin or dopamine, can facilitate synaptic strength and efficacy. Improved neuronal health and myelination can further support efficient synaptic communication.
Vesicles in an axon move towards the membrane due to the activity of molecular motors such as kinesin and dynein. These motors use ATP to move along microtubules in the cytoskeleton, carrying vesicles to their destination at the axon terminal. This movement is essential for the release of neurotransmitters during synaptic transmission.

Chemically Gated Channels.
Synaptic vesicles are found in the axon terminals of nerve cells.
Cardiorespiratory endurance
1. Nerve impulse reaches synaptic terminal. 2. Synaptic vesicles move to and merge with the presynaptic cell membrane of the motor neuron. 3. Acetylcholine is released into and diffuses across the synaptic cleft. 4. Acetylcholine binds to receptors on the postsynaptic cell membrane of the muscle fiber.

Perhaps "Do not MOVE around the room during an activity".
All you can really know for certain from a dream is that somewhere you thought of it, or had a memory of it. A dream is simply your brain trying to make sense of random synaptic activity during REM sleep. Your waking thoughts and memories are often shuffled around during this process which is what makes for such buzzer happenings.
No, RNA polymerase does not have exonuclease activity during transcription.
