Electrical charge resulting from the difference between positive and negative ions outside and inside the brain cell membrane is called?
Membrane potential
What has the author s Hagiwara written?
s. Hagiwara has written: 'Membrane potential-dependent ion channels in cell membrane' -- subject(s): Cell Membrane, Cell membranes, Ion channels, Ion exchange, Ion-permeable membranes, Membrane Potentials, Physiology
Term that refers to a membrane potential of about -70 mv?
Resting 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 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 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
What is nernst potential-?
The Nernst potential refers to the reversal potential of the membrane potential at which there is no net flow of a particular number of ion from one side of the membrane to another.
What organelle is responsible for gas exchange?
cell membrane
What slight shift away from the resting membrane potential in a specific region of the plasma membrane is called a?
local potential
What about a cell's resting membrane potential is FALSE?
The resting membrane potential is maintained by solely by passive transport processes.
