The electrical charge needed for nerve cell firing" is the result of ion exchange in and around the cell.
a. true
b. false

True.

Explanation:

Action potential occurs when the membrane potential of a cell changes. The electrical charge is needed for the transmission of action potential.

Sodium ions are present more outside the cell than inside whereas the concentration of potassium ions is higher inside the cell. The nerve cell firing occurs due to the unequal distribution and movement of ions inside and outside the cell. Three sodium ions are move into the cell whereas two potassium ions are move outside the cell. Hence, the electrical charge is required fro the neuron cell firing that results due to the ions exchange inside and outside of the cell.

Thus, the answer is true.
