What else can I help you with?
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?
Its too large
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 are 2 substances that diffuse freely across a cell membrane?
CO2, H2O, and O2 can all diffuse across a cell membrane. Also, small polar molecules (uncharged) and hydrocarbons easily diffuse across.
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.
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 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.
Why can oxygen diffuses across a cell membrane but a protein cannot?
Proteins are to large or Oxygen is much smaller than a protein.
How do you use diffuse in sentence?
Oxygen molecules diffuse across the membrane.
What part of the lung do oxygen molecules diffuse across into the bloodstream?
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.
Why can oxygen across a cell membrane but a 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 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.
What causes oxygen to enter and carbon dioxide to leave the capillaries?
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.
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.
