An electrical signal along a nerve cell triggers the secretion of a chemical signal in the form of neurotransmitter molecules. These diffuse across the synapse, the narrow space between the nerve cell and its target cell .The neurotransmitter stimulates the target cell. The transmission of a signal through the nervous system can also be considered an example of long–distance signaling. An electrical signal travels the length of a nerve cell and is then converted back to a chemical signal that crosses the synapse to another nerve cell o When epinephrine is mixed with glycogen phosphorylase and glycogen in a test tube, is glucose–1– phosphate generated?
