Question

Passive transport into cells is driven by a concentration gradient; a greater concentration of molecules on one side of the membrane.

Which direction would oxygen move across a cell membrane if there was a greater concentration of oxygen molecules on the inside of the
membrane?

A. It would continue to concentrate inside the cell.
B. The random diffusion of oxygen would balance and have no net effect.
C. Towards the outside of the cell.
D. None of the above.

Answer 1

A

Step-by-step explanation:

Towards the outside of the cell.

Answer 2

A. It will continue to concentrate inside the cell.

Step-by-step explanation:

Due to the higher concentration of oxygen molecules on the inside, oxygen molecules of the outside move to the inside and the more the oxygen molecules move inside the higher the concentration of the oxygen molecules on the inside.
