The membrane-bound enzyme system that restores and maintains the resting membrane potential is what pump?
The membrane-bound enzyme system responsible for restoring and maintaining the resting membrane potential is the sodium-potassium pump. It actively transports sodium ions out of the cell and potassium ions into the cell against their concentration gradients to establish the resting membrane potential.
Which channel is mainly responsible for the resting potential of a neuron?
The sodium-potassium pump is mainly responsible for establishing and maintaining the resting potential of a neuron. It actively transports sodium ions out of the cell and potassium ions into the cell against their concentration gradients, contributing to the overall negative membrane potential.
The sodium-potassium pump ejects two Na from the cell and then transports three K back into the cell in order to stabilize the resting membrane potential?
The sodium-potassium pump plays a key role in maintaining the resting membrane potential of a cell by actively pumping sodium ions out of the cell and potassium ions into the cell against their respective concentration gradients. This process helps establish the necessary ion concentration imbalances that are critical for generating and maintaining the electrical potential difference across the cell membrane.
After depolarization phase of an action potential the resting potential is restored by?
the action of the sodium-potassium pump, which actively transports sodium ions out of the cell and potassium ions into the cell. This process helps to re-establish the concentration gradients of sodium and potassium ions, returning the cell membrane to its resting potential.
Through the membrane of a resting neuron highly permeable to potassium ions its membrane potential does not exactly match the equilibrium potential for potassium because the neuronal membrane is?
The neuronal membrane also has ion channels for other ions besides potassium, such as sodium or chloride, that can influence the resting membrane potential. These other ions contribute to the overall equilibrium potential of the neuron, which affects its resting membrane potential. Additionally, the activity of Na+/K+ pumps helps establish and maintain the resting membrane potential, contributing to the slight difference from the potassium equilibrium potential.

Is it true that sodium-potassium pump ejects two Na from the cell and transports three K back into the cell in order to stabilize the resting membrane potential?
Yes, the sodium-potassium pump is an active transport mechanism that helps maintain the resting membrane potential of a cell by pumping out three sodium ions (Na+) for every two potassium ions (K+) it pumps in. This action helps to establish a slight negative charge inside the cell compared to the outside, which is necessary for normal cellular function.

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.
How does sodium potassium pumps support the efficient functioning of cells?
Sodium-potassium pumps maintain the electrochemical gradient across the cell membrane by pumping sodium out of the cell and potassium into the cell against their concentration gradients. This helps generate a negative membrane potential, which is necessary for various cellular processes like neurotransmission and muscle contraction. Additionally, the pump helps regulate cell volume and stabilize the resting membrane potential.

What restores the resting potential after the action potential passes through an axon?
The resting potential is restored after the action potential passes through an axon by the sodium-potassium pump, which actively transports sodium ions out of the cell and potassium ions into the cell. This process helps maintain the balance of ions inside and outside the cell, returning the membrane potential to its resting state.
Why resting membrane potential value sodium is closer to equilibrium of potassium?
The resting membrane potential value for sodium is closer to the equilibrium of potassium because the sodium-potassium pump actively maintains a higher concentration of potassium inside the cell and a higher concentration of sodium outside the cell. This leads to a higher permeability of potassium ions at rest, resulting in the resting membrane potential being closer to the equilibrium potential of potassium.
How does potassium affect the resting membrane potential of the cardiac cell?
Potassium plays a crucial role in maintaining the resting membrane potential of cardiac cells. It helps establish the negative charge inside the cell by moving out of the cell through potassium channels. This outward movement of potassium ions contributes to the polarization of the cell membrane, creating a negative resting membrane potential.
