What is the change of a cell membrane from positive to negative called?
A
Glycolysis
B
Action Potential
C
Temporal Summation
D
Electrolysis
Explanation: 

Detailed explanation-1: -Hyperpolarization is when the membrane potential becomes more negative at a particular spot on the neuron’s membrane, while depolarization is when the membrane potential becomes less negative (more positive).

Detailed explanation-2: -Repolarization refers to the change in membrane potential that returns it to a negative value just after the depolarization phase of an action potential has changed the membrane potential to a positive value.

Detailed explanation-3: -An action potential is a rapid sequence of changes in the voltage across a membrane. The membrane voltage, or potential, is determined at any time by the relative ratio of ions, extracellular to intracellular, and the permeability of each ion.
