What name is given to the trans-membrane proteins that allow the direct passage?
Integral proteins
What helps to allow materials to cross the plasma membrane?
Integral proteins - proteins which span the width of the membrane. This can be things such as channels and pumps.
What membrane components allow movement of non-polar substances across membrane?
Integral proteins allow movement of non-polar substances across membranes.
What channel proteins allow water to pass across the membrane?
Aquaporins
What are the special in cell membrane that allow materials such as water and sugar to pass through made of?
proteins
What substance on the plasma membrane helps identify chemical signals from outside the cell?
carbohydrates
What name is given to the trans-membrane proteins that allow the direct passage?
Integral proteins
What helps to allow materials to cross the plasma membrane?
Integral proteins - proteins which span the width of the membrane. This can be things such as channels and pumps.
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 are the special structures in the cell membrane that allow materials such as water and sugar through made of?
PROTEIN!!!!!!!!!!!!!!!!!!!!!!!!!
Which organelle in a cell allows for the passage of proteins?
Nuclear Pores, Openings in the nuclear membrane allow the passing of proteins.
Structure of a membrane?
Every cell membrane consists of phospholipid bi layer, specialized proteins, cholesterol and glycolipids.Every plasma membrane maintains a membrane resting potential across its surface. Sometimes clusters of cholesterol called lipid rafts are also found.
What membrane components allow movement of non-polar substances across membrane?
Integral proteins allow movement of non-polar substances across membranes.
What are the functions of a plasma membrane?
- Outer membrane of cell that controls cellular traffic- Contains proteins (left, gray) that span through the membrane and allow passage of materials- Proteins are surrounded by a phospholipid bi-layer
How do carriers proteins facilitate passive transport of molecules across a membrane?
Carrier proteins facilitate passive transport of molecules across a membrane by changing its shape, by using ATP, to allow a substance to pass through the membrane.
What channel proteins allow water to pass across the membrane?
Aquaporins
What are the special in cell membrane that allow materials such as water and sugar to pass through made of?
proteins
