Question

Can anyone help with number 9 question?

When thinking about an action potential
which one of the following statements is
TRUE?
O a.
O b. lonic conditions are restored after
repolarization by the actions of the
sodium-potassium (Na*-K*) pump,
whereby two Na+ ions are ejected
for every three K+ ions carried back
into the cell.
O c.
If a stimulus is strong enough,
hyperpolarization causes membrane
polarity to be completely reversed,
and an action potential is initiated.
O e.
A stimulus changes the permeability
of a "patch" of the membrane, and
sodium ions (Na+) diffuse rapidly
into the cell.
O d. During repolarization, sodium ions
diffuse rapidly into the cell.
The external side of the resting
membrane is slightly negative, d
its internal side is slightly positive.

Expert Solution

Step 1

The neurons are the nerve impulse generating and transmitting cells in the nervous system that are present in both central nervous system as well as in peripheral nervous system.

The generation of nerve impulse depends on the differential concentration of different ions and there permeability across the plasma membrane of the neuron.
