The entropy change of the system and the surroundings should be determined. Concept introduction: According to the second law of thermodynamics , the entropy of the entire universe increases with the time. Here, the universe is taken as an isolated system. Moreover, it is also said that the entropy change of the universe can never be negative. According to this law, Δ G = Δ H -T Δ S .

When sodium ions enter a neuron during depolarization, they trigger the opening of additional voltage-gated sodium channels nearby, creating a positive feedback loop where the influx of sodium ions further depolarizes the membrane, causing even more sodium channels to open and allowing more sodium ions to enter the cell, thus sustaining the depolarization process until the action potential peaks. But how and why exactly does the influx of sodium ions trigger more sodium channels to let in more sodium? Please explain
