Interpretation Introduction
Interpretation: The oxidation number for the elements
Concept introduction:
In a balanced equation the number of atoms of each element as a reactant is equal to the number of atoms of that element as a product.

Oxidation: Losing electrons, increasing oxidation number.

Interpretation Introduction
Interpretation: The oxidizing and reducing agents in the given reaction should be determined.
Concept introduction:
Change in the oxidation number of atoms involved in the reaction is one of the special characteristic of reduction reaction.
The number of electrons an atom tends to give up or gain in a chemical reaction is called oxidation number.
Oxidation: Losing electrons, increasing oxidation number.
Reduction: Gaining electron, decreasing oxidation number.
Oxidizing agent is a substance that removes electrons from another reactant in a chemical reaction and so it is reduced by taking electron onto itself and the reactant is oxidized by having its electron taken away.
Reducing agent is the element or compound in a redox reaction that donate an electron to another species and so it is oxidized.

Why did the authors worry about the temperature-dependent solubility of the carriers in thebilayer? How did the authors determine whether the effect of freezing the lipid bilayer wasto decrease the solubility of the carriers (nonactin and valinomycin) or whether the effectwas to impair their ability to diffuse through the membrane (decrease their mobility)?

- 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?
