The E_m for a Cell is -70 MV and E_Cl

Question

The Emfor a cell is -70 mV and EClis -80 mV. Increasing gClshould increase A) The driving force for Cl^- B) Outward flux of Cl^- and an inward current to depolarize the cell C) Inward flux of Cl^- and an outw ard current that hyperpolarizes the cell D) Inward flux of Cl^- and an inward current to depolarize the cell E) Outward flux of Cl^- and an outward current to hyperpolarize the cell

Accepted Answer

Increasing gCl (conductance for Cl-) would increase the inward flux of Cl- because Cl- ions would move from a higher concentration outside the cell to a lower concentration inside, given the cell's resting membrane potential is -70 mV and ECl is -80 mV. This movement of negatively charged ions into the cell would result in an outward current that hyperpolarizes the cell, making the inside more negative.

The Em for a cell is -70 mV and ECl is -80 mV. Increasing gCl should increase

The E_m for a cell is -70 mV and E_Clis -80 mV. Increasing g_Cl should increase
