Question

Which of the following cells would have a greater electrical attraction for sodium ions to enter the cell?

a) A cell with a membrane potential of -70 mV
b) A cell with a membrane potential of +30 mV
c) A cell with a membrane potential of -20 mV
d) A cell with a membrane potential of 0 mV

Answer 1

A cell with a membrane potential of +30 mV would have a greater electrical attraction for sodium ions to enter the cell.

Step-by-step explanation:

The electrical attraction for sodium ions to enter a cell is determined by the membrane potential across the cell's membrane. A cell with a more positive membrane potential will have a greater electrical attraction for sodium ions to enter the cell. In this case, option b) A cell with a membrane potential of +30 mV would have a greater electrical attraction for sodium ions to enter the cell compared to options a), c), and d).
