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.

This describes the ionic distribution across the cell membrane, where sodium (Na+) concentration is higher outside the cell and potassium (K+) concentration is higher inside the cell. This gradient is maintained by the sodium-potassium pump, a vital mechanism for cell function including nerve impulse transmission.

Which membrane protein is responsible for restoring the original concentration of Na plus and K plus?
The sodium-potassium pump, also known as the Na+/K+-ATPase, is responsible for restoring the original concentration of sodium and potassium ions across the cell membrane. This pump actively transports three sodium ions out of the cell in exchange for two potassium ions pumped into the cell, using ATP energy to maintain the concentration gradients.
What best describes the Na plus and K plus concentrations across a neuron's plasma membrane?
Na+ concentration is higher outside the neuron than inside, while K+ concentration is higher inside the neuron than outside. This concentration gradient is maintained by the Na+/K+ pump, which actively transports Na+ out of the cell and K+ into the cell, contributing to the resting membrane potential of the neuron.
What creates a Na concentration gradient in the proximal tubule?
The Na concentration gradient in the proximal tubule is created by Na+/K+-ATPase pumps on the basolateral membrane actively pumping Na+ out of the cell, generating a low intracellular Na+ concentration. This drives passive reabsorption of Na+ from the lumen of the tubule into the cell down its electrochemical gradient.
What hormone regulates Na plus and K plus ion concentration?
aldosterone
How does the inside of the resting neuron compare to the outside in terms of electrical charge and Na plus concentration?
The inside of a resting neuron is negatively charged compared to the outside, due to the higher concentration of negatively charged ions inside. Specifically, at resting membrane potential, there is a higher concentration of sodium ions outside the neuron compared to inside.

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.
During depolarization what diffused into the cell?
During depolarization, sodium ions diffuse into the cell through voltage-gated sodium channels. This influx of positively charged sodium ions causes the membrane potential to become less negative, leading to the depolarization of the cell.
In a 200-ml sample of 0.030 M Na3P04 what is the concentration of Na plus?
The concentration of Na+ in Na3PO4 is 0.090 M. This is because for every 1 mole of Na3PO4, there are 3 moles of Na+ ions. So in a 0.030 M solution of Na3PO4, the concentration of Na+ is 3 times that, which is 0.090 M.
What is difference between Na gate and Na pump?
The Na gate is a channel protein on the cell membrane that allows sodium ions to pass through, contributing to the generation of action potentials. The Na pump, or sodium-potassium pump, is an active transport protein that maintains the concentration gradient of sodium and potassium ions across the cell membrane by pumping sodium out of the cell and potassium into the cell.
The sodium-potassium pump transports what?
The sodium-potassium pump transports sodium ions (Na+) out of the cell and potassium ions (K+) into the cell against their concentration gradients, utilizing ATP for energy. This process helps maintain the resting membrane potential and is crucial for proper cell function.
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
Why with 1 mM ATP added to the cell interior left beaker and the extracellular space right beaker was all of the Na plus moved into extracellular space?
The addition of 1 mM ATP to the cell interior created an ion gradient that favored the movement of Na⁺ out of the cell into the extracellular space. This is due to the activation of Na⁺/K⁺ ATPase pump, which pumps Na⁺ out of the cell in exchange for K⁺ moving into the cell, resulting in more Na⁺ being present in the extracellular space.
What are spectator ions in Na plus plus OH- plus Cl- H2O plus Na plus plus Cl?
Na+ and Cl- are spectator ions.
