**
H¸N-C
H
Zwitterionic
H
Uncharged
OH
Select statements that explain why alanine is predominantly zwitterionic at its pl.
pk of alanine's amino group is more than its pl.
pk of alanine's carboxyl group is more than its pl.
PK of alanine's carboxyl group is less than its pl.
pk of alanine's amino group is less than its pl.
Correct Answer

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
