What are two factors that help maintain the resting membrane potential of a typical nerve cell?
Yes, some quantity of energy is needed to maintain and develop resting potential of cell's membrane during the stages 1 and 2 of resting potential forming
Cell uses energy of ATP at these stages for sodium potassium pump to create difference in K and Na ion concentration inside the cell and outside. For transportation 2 ions of potassium inside and 3 sodium ions outside the cell one molecule of ATP is needed

What is a resting motor neuron expected to do?
exhibit a resting potential that is more negative than the "threshold" 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.
What about a cell's resting membrane potential is FALSE?
A false statement about a cell's resting membrane potential could be that it does not involve the movement of ions across the cell membrane. In reality, the resting membrane potential is primarily due to the unequal distribution of ions, such as sodium and potassium, across the membrane, maintained by ion channels and pumps.
Term that refers to a membrane potential of about -70 mv?
Resting membrane potential is typically around -70mV and is maintained by the activity of ion channels that allow for the passive movement of ions across the cell membrane.
During an action potential hyperpolarization beyond more negative to the resting membrane potential is primarily due to?
Potential hyperpolarization are more negative to the resting membrane potential because of voltage. This is taught in biology.

What is the relationship between membrane potential and resting potential in a cell?
The resting potential of a cell is the membrane potential when the cell is at rest, typically around -70 millivolts. Membrane potential refers to the difference in electrical charge across the cell membrane. Resting potential is a type of membrane potential that is maintained when the cell is not actively sending signals.
What about a cell's resting membrane potential is FALSE?
A false statement about a cell's resting membrane potential could be that it does not involve the movement of ions across the cell membrane. In reality, the resting membrane potential is primarily due to the unequal distribution of ions, such as sodium and potassium, across the membrane, maintained by ion channels and pumps.
Electrical charge resulting from the difference between positive and negative ions outside and inside the brain cell membrane is called?
This electrical charge is called the resting membrane potential. It is generated by the unequal distribution of ions such as sodium, potassium, chloride, and calcium inside and outside the cell. The resting membrane potential plays a crucial role in cell communication and proper functioning of the nervous system.

The resting membrane potential of a neuron is about?
-70mV
Where are the leak channels located on a neuron and how do they contribute to the resting membrane potential?
Leak channels are located on the cell membrane of a neuron. These channels allow ions, such as potassium and sodium, to passively move in and out of the cell. This movement of ions helps to establish and maintain the resting membrane potential of the neuron, which is essential for its normal functioning.
Term that refers to a membrane potential of about -70 mv?
Resting membrane potential is typically around -70mV and is maintained by the activity of ion channels that allow for the passive movement of ions across the cell membrane.
Why is the inside of the cell membrane negatively charged at resting potential?
The inside of the cell membrane is negatively charged at resting potential because of an unequal distribution of ions, specifically more negatively charged ions inside the cell compared to outside. This creates an electrical potential difference across the membrane, known as the resting membrane potential.
What is the significance of the equilibrium potential in determining the resting membrane potential of a cell at cl equilibrium?
The equilibrium potential is important in determining the resting membrane potential of a cell because it represents the voltage at which there is no net movement of ions across the cell membrane. At this point, the concentration gradient and electrical gradient for a specific ion are balanced, resulting in a stable resting membrane potential.
During an action potential hyperpolarization beyond more negative to the resting membrane potential is primarily due to?
Potential hyperpolarization are more negative to the resting membrane potential because of voltage. This is taught in biology.
