Which of the following is NOT a difference between graded potentials and action potentials?
Graded potentials can result from the opening of chemically gated channels; action potentials require the opening of voltage-gated channels.

Graded potentials occur along dendrites, whereas action potentials occur along axons.

Spatial summation is used to increase the amplitude of a graded potential; temporal summation is used to increase the amplitude of an action potential.

Greater stimulus intensity results in larger graded potentials, but not larger action potentials.
