question 7 (1 point)
how many sodium ions are being transported outside the cell by the sodium potassium pump?
1
2
3
4

Explanation:

The sodium - potassium pump (Na⁺/K⁺ - ATPase) functions by transporting 3 sodium ions ($\text{Na}^+$) out of the cell and 2 potassium ions ($\text{K}^+$) into the cell for each molecule of ATP that is hydrolyzed. So the number of sodium ions transported outside the cell by the sodium - potassium pump is 3.

Answer:

1. 3
