Its too large
Proteins are to large or Oxygen is much smaller than a protein.
No, oxygen cannot directly diffuse across a cell membrane. Instead, it crosses the cell membrane with the help of specific transport proteins, such as aquaporins and oxygen channels. These proteins facilitate the movement of oxygen from areas of high concentration to low concentration.
CO2, H2O, and O2 can all diffuse across a cell membrane. Also, small polar molecules (uncharged) and hydrocarbons easily diffuse across.
Oxygen molecules are small and non-polar, allowing them to easily pass through the phospholipid bilayer of the cell membrane via simple diffusion. In contrast, protein molecules are typically larger and may require specific transport proteins or channels in the membrane for facilitated diffusion or active transport to cross the membrane.
H2O CO2 O2 hope this helps

Oxygen is a small, non-polar molecule that can passively diffuse across the lipid bilayer of a cell membrane. Proteins, on the other hand, are larger and more complex molecules that cannot pass through the hydrophobic core of the membrane. Instead, proteins are transported into or out of cells through specific channels or transporters.

Its too large
Oxygen molecules diffuse across the alveolar membrane in the lungs into the bloodstream. This is where gas exchange occurs, with oxygen moving from the alveoli into capillaries surrounding the alveoli.
Oxygen and carbon dioxide are the two important gases that diffuse across the respiratory membrane. Oxygen moves from the alveoli into the bloodstream, while carbon dioxide moves from the bloodstream into the alveoli to be exhaled.
Carbon dioxide, oxygen and some nonpolar molecules diffuse easily.
Oxygen and carbon dioxide get into and out of cells via diffusion. The gases diffuse across the thin capillary wall, and then diffuse across the cell membrane.
