WebA graded potential is produced when a ligand opens a ligand-gated channel in the dendrites, allowing ions to enter (or exit) the cell. For example, Na + will enter the cell … WebThe magnitude of the graded potential is proportional to the strength of the stimulus. Hence, a strong stimulus might result in a 10mV change in the membrane potentials, while a weaker stimulus may produce only a 5mV change. Graded potentials are also localized to a small area of the cell membrane and are sometimes called local potentials.
