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?
Many different things cannot pass through, including sugars, salts and proteins. However, oxygen, water and carbon dioxide can simply diffuse 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.
Why can oxygen diffuses across a cell membrane but a protein cannot?
Proteins are to large or Oxygen is much smaller than a protein.
Why can oxygen diffuse across a cell membrane but a protein cannot-?
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 much smaller than a protein

Why can oxygen diffuse across a cell membrane but a protein can?
Its too large
Why can oxygen diffuse across a cell but a protein cannot?
Oxygen is much smaller than a protein.proteins are too largeDifference in size
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 do oxygen molecules easily diffuse across a cell membrane while protein molecules do not?
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.
Can oxygen diffuse across a cell membrane?
Yes, how else would our cells obtain oxygen?
