The Depolarization of the Membrane Due to a Stimulus Is

Multiple Choice

The depolarization of the membrane due to a stimulus is a regenerative mechanism meaning that, once sodium gates begin to open, even more sodium gates will be activated leading to a larger inflow of sodium ions and more depolarization until it is terminated when sodium gates close. This is an example of

A) inhibitory graded potentials.
B) negative feedback.
C) excitatory graded potentials.
D) positive feedback.
E) electrotonic conduction.
