Question
Chapter 12, Problem 16DYKB
Summary Introduction
To determine:
The similarity and differences between the graded potential and an action potential.
Concept introduction:
The unequal distribution of positive and negative charge across the cell membrane results in membrane potential of a cell. When the membrane potential of an axon in a specific location rises and falls, it causes a series of electrical response or action potential. Action potential helps in the communication between cells.
