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

Why can oxygen defuse across a cell membrane but protein cannot?
Because an oxygen atom is very small and a protein is made up of lots of atoms and is therefore very large by comparison.
Why can oxygen diffuses across a cell membrane but Protein can not?
Its too large
What large molecules need help getting across cell membrane?
In general, molecules that cannot diffuse across the cell membrane are either very large, such as starches and fats, or very polar.
Why can oxygen water and carbon dioxide move through the cell membrane but salt and protein cannot?
That depend on size and the charge.Large molecules and charged molecules cannot move freely
What substance cannot pass directly through the phospholipids of the plasma membrane?
Large polar molecules and charged molecules cannot pass directly through the phospholipids of the plasma membrane because the phospholipid bilayer is impermeable to them. Instead, these molecules rely on specific transport proteins like channels or carriers to facilitate their movement across the membrane.
Why can oxygen diffuse across a cells membrane but a protein cannot?
Proteins are to large or Oxygen is much smaller than a protein.

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

Why can oxygen diffuse across a cell membrane but a protein can't?
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.
Can oxygen diffuse across a cell 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.
What molecule is used to transport oxygen and act as an enzyme and transport materials across the cell membrane and forms the filaments of muscles?
Protein.

Why can oxygen diffuse across a cell but a protein cannot?
Oxygen is much smaller than a protein.proteins are too largeDifference in size
Why do oxygen molecules easily diffuse across a cell membrane while protein molecules do not?
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.
