A graph-labelling activity aimed at A level Biology students. This worksheet is designed to help students to get to grips with the action potential graph, its key stages and what causes the changes in charge across the neurone membrane in terms of ion movement.
The values for resting and threshold potential are incorrect -70mv and -55mv but you have -60 and -40

Hi there thanks for the feedback, the values are correct. Both those values live within a range and some exam boards quote specific values that differ. Please see below…
Resting potential refers to the stable electrical charge across a neuron's membrane when it is not actively sending signals, typically ranging from -75 to -55 mV.
