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.
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.
What two important gases diffuse across the respiratory membrane?
Oxygen and carbon dioxide are the two important gases that diffuse across the respiratory membrane. Oxygen moves from the alveoli into the bloodstream, while carbon dioxide moves from the bloodstream into the alveoli to be exhaled.
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
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 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
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.
Why can oxygen diffuse access a cell membrane but a protein cannot?
Oxygen molecules are small and non-polar, allowing them to easily pass through the lipid bilayer of a cell membrane via simple diffusion. Proteins, on the other hand, are typically large and polar molecules that cannot readily pass through the hydrophobic core of the lipid bilayer. Instead, proteins rely on specific transport mechanisms like protein channels or carriers to cross the cell membrane.
Does oxygen diffuse through a semipermable membrane?
yes
What types of molecules can diffuse through the cell membrane without using a channel protein?
Small, non-polar molecules like oxygen, carbon dioxide, and water can diffuse through the cell membrane without the need for a channel protein. Their small size and non-polar nature allow them to passively pass through the lipid bilayer of the membrane.
Which particles can diffuse easily througn a cell membrane?
Oxygen
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.
