Term that refers to a membrane potential of about -70 mv?
Resting membrane potential
Which is the correct term for the movement of an electrical charge across a membrane?
Potential difference.
The term voltage regulated means that the?
membrane voltage gated ion channels open and close with changes in the membrane potential
The movement of the water across a membrane is termed?
The term used is osmosis. the direction of movement across the membrane is dependent on the concentration of solutes (known as the solute potential) which directly effects the osmotic potential.
What is the charge on the inside membrane during the resting membrane potential?
The resting membrane potential of a typical neuron is around -65mV

action potential

Electrical charge resulting from the difference between positive and negative ions outside and inside the brain cell membrane is called?
Membrane potential
What is the charge on the inside membrane during the resting membrane potential?
The resting membrane potential of a typical neuron is around -65mV
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 meant by the following statement about the cell membrane The cell membrane is said to be semipermeable.?
It is very selective about what it allows to pass through.
What is a difference in electric charge called?
The chemical gradient refers to the imbalance of substances across the membrane. The Electrical Gradient refers to the difference of charges between substances on different sides of the Membrane. The Electrochemical Gradient refers to the combination of the previous two gradients. The short answer is MEMBRANE POTENTIAL.
