All particles trying to get into the cell must get through the cell membrane. The cell membrane is selectively permeable, which means that it can select what goes in and what goes out. The structure of a cell membrane is called a lipid bilayer, which is two layers of phospholipids.
The cell membrane is where oxygen can pass.
Oxygen is lipid soluble therefore it can pass directly through the cell membranes of the capillaries.
The cell membrane contains receptors that allow or block passage of various molecules.
Oxygen is much smaller than a protein.proteins are too largeDifference in size
The membrane
Carbohydrate molecules and oxygen enter the cell during cellular resperation.

Although the cell wall is tough, many materials, including water and oxygen, can pass through easily.
Oxygen is lipid soluble therefore it can pass directly through the cell membranes of the capillaries.
The Cell Membrane
Oxygen
the cell
It keeps the cell in shape, works as a protection and lets oxygen and nutrition pass into the cell

I'm not entirely sure but, I think it is the cell membranes.
