Term that refers to a membrane potential of about -70 mv?
Resting membrane potential
What would be the most immediate effect of doubling the number of Na leakage channels in the plasma membrane?
The resting membrane potential would become less negative (more positive).
What is the charge on the inside membrane during the resting membrane potential?
The resting membrane potential of a typical neuron is around -65mV
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.
What is membrane polarity?
-70 mV this potential difference in a resting neuron (Vr) is called the resting membrane potential, and the membrane is said to be polarized.
What is the effect on the heart function in the case of hypokalemia and hyperkalemia?
Hypokalemia and hyperkalmia both can have effects on the heart function. Hypokalemia and hyperkalemia can cause cardiac arriythmias.
Excessive vomiting for example can deplete the body's K reserves and abnormally lower the potassium concentration in the plasma hypokalemia The membrane potential of cells under the influence of?
somewhere between -65 and -90 mV
What effect does the leaking of potassium across the membrane have on the membrane potential of Kevin's neurons?
It makes the inside of the neurons more negative.
Electrical charge resulting from the difference between positive and negative ions outside and inside the brain cell membrane is called?
Membrane potential
Term that refers to a membrane potential of about -70 mv?
Resting membrane potential
What two forces drive the passive transport of ions across a membrane?
Two forces drive the passive transport of ions across a membrane: -the concentration gradient of the ions -the effect of membrane potential (voltage) on the ions
What would be the most immediate effect of doubling the number of Na leakage channels in the plasma membrane?
The resting membrane potential would become less negative (more positive).
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 does the difference in the K and Na concentration on either side of the plasma membrane and permeability of the membrane to those ions generate?
resting membrane potential
