What else can I help you with?
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.
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.
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.
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 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.
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 diffuse across a cells membrane but a protein cannot?
Proteins are to large or Oxygen is much smaller than a protein.
What structure does oxygen diffuses through but sodium ion may need active transport?
A semipermeable membrane
How does oxygen gets from the air to your blood?
Oxygen is inhaled through the lungs where it diffuses across the lung membrane into tiny blood vessels called capillaries. From there, oxygen binds to hemoglobin in red blood cells and is transported throughout the body to be used by cells for energy production.
