Question
Chapter 16, Problem 15P
Interpretation Introduction
Interpretation:
The reason for more importance of regulation of phosphofructokinase by energy charge in muscles in comparison to liver should be determined.
Concept introduction:
Glycolysis is also termed as Embden-Meyerhof pathway. It involves the breakdown of one molecule of glucose into two molecules of pyruvate. During this reaction two molecules of ATP are used up in the preparatory phase. Further, in the payoff phase two molecules of ATP and two molecules of NADH are produced.

How does a voltage-gated sodium channel work? Specifically, how and why does a change in voltage trigger their opening? Please be detailed
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
