What else can I help you with?
What organelle transports large particles out of the cell?
cell membrane
What happens if a molecule is too large to go through a membrane?
The molecule will be transported across the membrane by way of a transport protein or protein channel.
Why can oxygen diffuses across a cell membrane but Protein can not?
Its too large
Does egg albumin moves across a plasma membrane?
No, egg albumin is a large protein molecule that cannot pass through the plasma membrane on its own. It would require specific transport mechanisms, such as endocytosis or facilitated diffusion, to cross the membrane.
What part of the membrane would help a large protein molecule enter the cell?
Globular Proteins
Why can oxygen diffuse across a cell membrane but a protein cannot-?
Proteins are to large or Oxygen is much smaller than a protein.
How does a large particle leave a cell by a active transport?
It requires energy, and a protein carrier molecule. The large particle binds to the protein carrier on the inside of the cell. It is then transported across the membrane as a result of a conformational change in the protein (think of it flipping), and then it is released on the outside of the cell. Again, this requires some source of energy.
How does facilitated diffusion occur through a protein channel?
Facilitated diffusion occurs through a protein channel by allowing specific molecules to pass through the cell membrane with the help of a protein channel. The protein channel acts as a tunnel that facilitates the movement of molecules that are too large or polar to pass through the membrane on their own. The molecules bind to the protein channel, which changes shape to allow them to pass through, ultimately helping them move across the membrane.
