There is a greater concentration of Na plus outside and there is a greater concentration of K plus inside the cell. When the stimulus is delivered, the permeability of the membrane is changed, and Na plus diffuses into the cell, initiating the depolarization of the membrane.

Which membrane protein is responsible for restoring the original concentration of Na plus and K plus?
Sodium potassium pump is responsible for restoring the original concentration of Na plus and K plus.
How does the inside of the resting neuron compare to the outside in terms of electrical charge and Na plus concentration?
The concentration of negatively charged proteins and positively charged potassium ions, K+, is greater inside the cell than outside. In contrast, the concentration of sodium ions, Na+, is greater outside the cell than inside. The concentrations of Na+ and K+ ions are partly due to the action of the sodium-potassium pump, which actively moves Na+ out of cells while moving K+ in.
What hormone regulates Na plus and K plus ion concentration?
aldosterone
What best describes the Na and K concentrations across a neuron's plasma membrane?
The Na concentration is higher outside of the neuron's plasma membrane, while the K concentration is higher inside the neuron's plasma membrane. This creates an electrochemical gradient that allows for the generation and transmission of electrical signals in neurons.
What bonds is the strongest Na-I or Na-Cl or K-I or K-Cl?
In neurons, ________ ions are at higher concentration inside the cell and ________ ions are at higher concentration in the extracellular fluid. A) Cl; organically bound B) Cl; K C) K; Na D) Cl; Na E) Na; K

During depolarization what diffused into the cell?
During depolarization, the extracellular Na+ ions diffuse into the cell. These Na+ ions stimulate the reversal of the Na+/Ca2+ exchanger channel, thereby transporting 1Ca2+ ion intracellularly versus 3Na+ ions transported extracellularly. Ca2+ ions are also released from the sarcoplasmic reticulum (SR) storage - these too add to the intracellular Ca2+ concentration. The intracellular Ca2+ causes contraction. Over time, the result is Ca2+ overload which ultimately leads to cell death. Thus, the concentration of extracellular Na+ is directly related to the Ca2+ overload of a human cell. The higher the concentration of extracellular Na+ influx, the greater the chance of Ca2+ overload and cell death.

How does the concentration of H plus and OH- ions determine pH?
pH = - log([H+]) , pOH = - log([OH-] , pH + pOH = 14 [X] = concentration of X
In a 200-ml sample of 0.030 M Na3P04 what is the concentration of Na plus?
200 mL sample of 0,030 M Na3P04 contain 0,414 g sodium; the concentration of Na is 2,07 g/L.
Which has greater coagulating power Na plus or Al plus 3 Cl- or SO4 -2?
Na plus or Al 3plus, Al 3+ has greater coagulating powerCl- or SO4^2- , SO4^2- has greater coagulating power.Look at their net chargesNa+ has one chargeAl3+ has threeso Al3+ has greater coagulating power.Cl- has one chargeSO4^-2 has two.so SO4^2- has greater coagulating power
Does Na or Ne have a greater charge?
Na has a greater charge
What gradient moves Na plus into the cell during depolorization?
both the electrical and chemical gradients
