Question

BIOLOGY 354 e) b and c meable to CI- s per 2) A cell at rest at -70 mV, in physiological concentrations of ions, suddenly become (CI- channels open). How will this change the Vm? a) not much of a change b) Vm will go toward-65 mV c) Vm will go toward +55 mV d) a and b A cell is clamped at -80 mV and K+ channels are open. In which direction will the NET FLOW of K+ ions be? Assume physiological concentrations of ions. a) to the outside of the cell b) to the inside of the the cell c) no net flow 3)

Explanation / Answer

Option d is correct.

both a and b correct.

when a cell become permeable and then allows the incoming of chloride ions so the charge of the cell will slightly chanegs.

3.

through potassium channels potassium ions comes inside the cell from outside the cell.
