Question

oxygen gas (o₂) is carried to all of your organs and tissues through your bloodstream. activate your knowledge about diffusion and the permeability of cell membranes for specific molecules. what will most likely happen to the oxygen molecules in this diagram? oxygen will move from the blood into the muscle but it requires a protein channel to cross cell membranes. oxygen will move from the blood into the muscle by diffusing directly through cell membranes. you cannot determine the direction and mechanism of oxygen movement without more information. oxygen will move from the muscle into the blood by diffusing directly through cell membranes.

Explanation:

Oxygen is a small, non - polar molecule. Cell membranes are permeable to small non - polar molecules, and oxygen moves from an area of higher concentration (blood) to an area of lower concentration (muscle cells) by simple diffusion directly through the lipid bilayer of the cell membrane without the need for a protein channel.

Answer:

Oxygen will move from the blood into the muscle by diffusing directly through cell membranes.
