If the partial pressure of oxygen outside of a cell is 100 mmHg and the partial pressure of oxygen inside of a cell is 25 mmHg, which of the following statements is CORRECT?

Question

When there is a difference in partial pressure of a gas across a membrane, there will be a net movement of that gas from the area of higher partial pressure to the area of lower partial pressure until equilibrium is reached. In this case, the partial pressure of oxygen is higher outside of the cell than inside, so oxygen will move from outside the cell to inside the cell.
