The movement of relatively large particles across a plasma membrane via transport proteins?
... is called "facilitated diffusion".
What is the movement of relatively large particles across a plasma membrane via transport proteins called?
Facilitated Diffusionosmosis & diffusion
Which one moves faster across the cell membrane the large or the small?
Small particles move faster across the membrane.
What are Channel and carrier proteins?
Channel proteins are on the plasma membrane, selectively transport the solutes such as ions, small and large proteins across the membrane. Carrier proteins also membrane proteins that allow diffusion of different molecules. Both proteins are chemically made up of amino acids.
What happens if the particle is too large to get across the membrane?
The cell use something called a protein channel that helps larger particles across the cell membrane.
What molecules will move easily across the cell membrane: large proteins, starch, water, or DNA?
It depends on the membrane, but generally water is the only one that will move across unaided. The rest are too large.
Why are proteins and polysaccharides cannot be transported across a cell membrane by carrier proteins?
They are too large to be transformed by carrier proteins. They are moved across by Vesicles instead.
What can across the membrane with assistance?
large or polar molecules such as proteins, glucose or ions like Na+/K+
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 cells membrane but a protein cannot?
Proteins are to large or Oxygen is much smaller than a protein.
Why can oxygen diffuses across a cell membrane but a protein cannot?
Proteins are to large or Oxygen is much smaller than a protein.
Why do cells need carriers proteins that transport glucose?
Large molecules, such as glucose, are not able to pass through the cell membrane. Therefore proteins are needed to transport them across.
