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.

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 is a small, nonpolar molecule that can easily pass through the lipid bilayer of cell membranes by simple diffusion without the need for a specific transport protein. This allows oxygen to move from areas of high concentration to areas of low concentration, such as from the lungs into the bloodstream.
Glucose is too big to pass throught.
Oxygen molecules are small and non-polar, allowing them to easily pass through the lipid bilayer of a cell membrane via simple diffusion. Proteins, on the other hand, are typically large and polar molecules that cannot readily pass through the hydrophobic core of the lipid bilayer. Instead, proteins rely on specific transport mechanisms like protein channels or carriers to cross the cell membrane.
Proteins are to large or Oxygen is much smaller than a protein.

Oxygen molecules diffuse across the membrane.
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 and carbon dioxide are two substances that can freely diffuse across a cell membrane due to their small size and non-polar nature.

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.
