Question

The diagram below shows the relative concentration of molecules inside and outside of a cell. Which statement best describes the general direction of diffusion across the membrane of this cell?
(1) Glucose would diffuse into the cell.
(2) Protein would diffuse out of the cell.
(3) Carbon dioxide would diffuse out of the cell.
(4) Oxygen would diffuse into the cell.
HELP PLEASE

Answer 1

Answer:

4

Explanation:

This is the answer because I have tested it and got it correct. As oxygen-rich (and carbon dioxide-poor) blood travels by a cell the oxygen diffuses through the cell membrane to the area of lower concentration inside the cell. It can do this easily because the oxygen molecule (O2) is very small and has no charge or polarity. The oxygen is used up rapidly by mitochondria.
