There is a greater concentration of na plus and there is a greater concentration of k plus in the cell?
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.
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
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.
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 hormone regulates Na plus and K plus ion concentration?
aldosterone

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.
What sort of ion distributions are established and maintained by Na -K pump activity?
high Na+ concentration in the extracellular fluid; high K+ concentration in the cytoplasm

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.
What concentration gradients are established and maintained by the sodium-potassium exchange pump?
high Na+ concentration in the extracellular fluid; high K+ concentration in the cytoplasm

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.
What is the song that goes Hoo ha hoo ha Na na-na na na na-na na na na-na in the video The Human Ipod?
Best Friend - Toy Box
What hormone regulates Na plus and K plus ion concentration?
aldosterone
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.
