What about a cell's resting membrane potential is FALSE?
The resting membrane potential is maintained by solely by passive transport processes.
The membrane potential of a cell favors?
movement of cations into the cell
Why is there a resting membrane potential across the cell membrane?
sodium/potassium pump
What ion determines the resting membrane potential of nerve and muscle?
The concentrations on Na+ outside the cell and concentrations of K+ inside the cell determine the resting membrane potential.
When a cell is at rest?
resting potential
What is resting potential?
A rest potential is the potential difference between two sides of the membrane of nerve cells when the cell is not conducting an impulse. =)
What is the electrical potential across the cell membrane of a nerve cell or muscle cell when the cell is not active?
resting potential
It is the membrane potential of a neuron at rest?
Yes,the membrane potential of a neuron is at rest because it is the difference in electrical charge between inside and outside a resting neuron.
Electrical charge resulting from the difference between positive and negative ions outside and inside the brain cell membrane is called?
Membrane potential
The step in which the membrane potential returns to rest?
Depolarization

If a resting potential becomes more negative what happens to the cell?
When the membrane potential becomes more negative it is being hyperpolarized. Remember the resting membrane potential is already at a negative state (~70mV). So if you are making a comparison of a membrane potential that is hyperpolarized in comparison to a resting membrane potential, the resting membrane potential is said to be more depolarized.When the membrane potential becomes more positive it is called depolarization.
What is polar cell?
It's called membrane potential.
What is a polar cell?
It's called membrane potential.
What factors contribute to the membrane potential of a cell?
There are many factors that contribute to the membrane potential of a cell. The driving force of ions which are a summation of voltage gradient and concentration gradient are an important one. Also other proteins and amino acids contribute to the cell's membrane potential.
