C) The synaptic cleft uses the action potential to transmit a chemical signal to the postsynaptic cell.
D) Neurotransmitter receptors are located on the axons terminals of cells.

Question

Quizplus · Accepted Answer

Chemical synapses rely on the release of neurotransmitter molecules to transmit a signal to the postsynaptic cell. The synaptic cleft is the gap between the presynaptic and postsynaptic cells where the neurotransmitters are released. The action potential does not cross the synaptic cleft; instead, it triggers the release of the neurotransmitter. The neurotransmitter then diffuses across the synaptic cleft to bind to receptors on the postsynaptic cell. This binding triggers a response in the postsynaptic cell, leading to the transmission of the signal. Gap junctions, on the other hand, allow for direct electrical coupling between cells and do not rely on the release of neurotransmitters.
