Explain about force-gated channel, Biology

Assignment Help:

At 1:00AM, Neuron A is at rest with membrane potential equal to -70 millivolts; it is producing no action potentials.  The threshold for an action potential in neuron A is -55 millivolts. 

There is a large amount of force-gated channel X spanning proteins that are located in the plasma membrane of the cell body of neuron A.  Channel X is the only force-gated channel in neuron A.  At 1:00 AM, there are no external forces on the cell body of neuron A and all the force-gated channel X's channels are closed.  At 1:05 AM, force is applied to the cell body of neuron A and all the force-gated channel X's channels are open.  If the equilibrium potential for force-gated channel X is

A. -58 millivolts, then at 1:05AM there will be an increase in membrane voltage and an action potential following the application of force to the cell body of neuron A.

B. -70 millivolts, then at 1:05AM there will be a decrease in membrane voltage following the application of force to the cell body of neuron A.

C. -60 millivolts, then at 1:05AM there will be an increase in membrane voltage following the application of force to the cell body of neuron A.
