If the neuron is stimulated such that its membrane potential changes to 50 mV, what is the sign of the driving force for Cl- ions and in which direction will these ions move across the membrane?
a. Positive driving force; Cl- moves into the cell
b. Positive driving force; Cl- moves out of the cell
c. Negative driving force; Cl- moves into the cell
d. Negative driving force; Cl- moves out of the cell.
Answer: d. Negative driving force; Cl- moves out of the cell.
- Option d is correct. Negative driving force; Cl- moves out of the cell.
- Because when chloride are come out from cell it make positive potential inside neuron.because it removes negative charge from neuron.
- for anions negatively charged ions such as Chloride where a positive driving force predicts ion movement into the cell (influx), and a negative driving force predicts ion movement out of the cell (efflux)
