Answer:
Chemical signal helps to coordinate the action between neighbouring cell
Step-by-step explanation:
Cell signaling is an important process that occur in every living cell of human body and helps those cells to exert their biochemical and physiological functions.
chemical signals coordinates the actions between neighbouring cell.For example Acetyl choline is released during neurotransmision from the presynaptic membrane membrane crosses the synaptic cleft and binds to the receptor present in the surface of post synaptic cells .This ultimately result in the generation of depolarization which is the first step of action potential.
Depolarization then helps in the opening of Na+ ion channels ,through which Na+ ion ion enter the cell that coverts the negative potential of the cell to a positive value.
