Because an oxygen atom is very small and a protein is made up of lots of atoms and is therefore very large by comparison.

Its too large
Oxygen can diffuse across a cell membrane because it is a small, non-polar molecule that can easily pass through the lipid bilayer of the membrane. In contrast, proteins are large and often polar or charged, making it difficult for them to traverse the hydrophobic core of the lipid bilayer without assistance. Proteins typically require specific transport mechanisms, such as channels or carriers, to facilitate their movement across the membrane.
Oxygen can diffuse across the cell membrane due to its small size and nonpolar nature, allowing it to easily pass through the lipid bilayer without the need for transport proteins.

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.
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.

Oxygen can diffuse across the cell membrane because it is a small, nonpolar molecule, allowing it to pass through the lipid bilayer easily due to the hydrophobic nature of the membrane. In contrast, proteins are larger and polar or charged, which prevents them from readily crossing the lipid bilayer without assistance. Instead, proteins typically require specific transport mechanisms, such as channels or carriers, to facilitate their movement across the membrane. This difference in size and polarity is key to the distinct transport processes for oxygen and proteins.
