Its too large
What else can I help you with?
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.
How does oxygen get in and out of plasma membrane?
Oxygen, O2, is a small enough molecule that it diffuses diwn it's concentration gradient into the cell and rather easily foes through the plasma membrane. Many small molecules can do this.
How does gaseous exchange take place in Amoeba?
Gaseous exchange in Amoeba occurs through diffusion. Oxygen from the surrounding environment diffuses into the cell across the cell membrane, while carbon dioxide produced by cellular respiration diffuses out of the cell. This process allows for the exchange of gases to support the metabolic activities of the cell.
How does paramecium get oxygen?
Paramecium absorbs oxygen directly from its surroundings through a process called diffusion. Oxygen from the water enters the paramecium's cell membrane and diffuses into the cytoplasm, where it is used in cellular respiration to produce energy.
Why can oxygen diffuses across a cell membrane but a protein cannot?
Proteins are to large or Oxygen is much smaller than a protein.
What process is responsible for transport of oxygen and carbon dioxide across the alveolar membrane?
The process responsible for the transport of oxygen and carbon dioxide across the alveolar membrane is called diffusion. Oxygen diffuses from the alveoli into the blood, while carbon dioxide diffuses from the blood into the alveoli. This process is driven by differences in partial pressures of these gases on either side of 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 oxygen diffuses from the alveoli into the blood?
Oxygen diffuses from the alveoli into the blood because of a concentration gradient. The partial pressure of oxygen in the alveoli is higher than in the blood, so oxygen moves across the thin membrane of the alveoli into the blood to reach equilibrium.
How does amoeba obtain oxygen?
Amoebas obtain oxygen through diffusion. Oxygen from the surrounding environment diffuses across their cell membrane and into their cytoplasm, where it is used for cellular respiration to generate energy.
Why can oxygen diffuse across a cell membrane but a protein cannot-?
Proteins are to large or Oxygen is much smaller than a protein.
What structure does oxygen diffuses through but a sodium ion may need active transport?
Oxygen can diffuse through the cell membrane, which is selectively permeable to small non-polar molecules. On the other hand, sodium ions are charged and larger, so they typically require active transport mechanisms such as protein pumps to move across the cell membrane.

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.
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.
