Oxygen is much smaller than a protein
Its too large
All gases diffuse to a homogenous phase.
Oxygen passes through the membrane by diffusion. Most other molecules must be transported (carried) across by proteins which reside within the cell membrane.
Glucose is too big to pass throught.
no; amino acids build protein and oxygen is not a protein. oxygen is not built, but rather inhaled from the environment and then used in cellular respiration

Proteins are to large or Oxygen is much smaller than a protein.

Yes, how else would our cells obtain oxygen?
Oxygen molecules diffuse across the membrane.
Cell membrane is semipermeable and oxygen molecules have size required for easy passqge while Glucose molecules do not have that size required for easy passage.
oxygen and carbon dioxide
CO2, H2O, and O2 can all diffuse across a cell membrane. Also, small polar molecules (uncharged) and hydrocarbons easily diffuse across.
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.
