What name is given to the trans-membrane proteins that allow the direct passage?
The name given to the trans-membrane proteins that allow the direct passage of small molecules across the cell membrane is "channel proteins." They form channels or pores that facilitate the movement of specific ions or molecules across the membrane.
The classes of membrane proteins that permit water and solutes to bypass the lipid portion of the cell membrane are?
The classes of membrane proteins that allow water and solutes to bypass the lipid bilayer of the cell membrane are known as channel proteins and carrier proteins. Channel proteins form pores or channels that allow specific ions or molecules to pass through, while carrier proteins bind to specific solutes and undergo a conformational change to transport them across the membrane.
What is a membrane protein that allows specific charged molecules to pass through from one side of the membrane to another?
Ion channel proteins are membrane proteins that allow specific charged ions, such as sodium, potassium, or calcium, to pass through from one side of the membrane to another. They play a critical role in maintaining cell function and communication.
What membrane components allow movement of non-polar substances across membrane?
Integral proteins allow movement of non-polar substances across membranes.
What organic molecules allow ions and polar molecules to pass through the plasma membrane?
Integral membrane proteins, specifically channel proteins and carrier proteins, facilitate the passage of ions and polar molecules through the plasma membrane. Channel proteins form specific pores that allow ions to move down their concentration gradients, while carrier proteins undergo conformational changes to transport polar molecules across the membrane. These proteins are essential for maintaining cellular homeostasis by regulating the movement of substances in and out of the cell.

What structural feature on the surface of a plasma membrane allows cells to recognize one another?
Glycoproteins and glycolipids are structural features on the surface of the plasma membrane that allow cells to recognize one another. These molecules can act as cell identifiers by creating unique patterns that other cells can identify and respond to.
What are the special structures in the cell membrane that allow materials such as water and sugar through made of?
PROTEIN!!!!!!!!!!!!!!!!!!!!!!!!!
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.

Which organelle in a cell allows for the passage of proteins?
Nuclear Pores, Openings in the nuclear membrane allow the passing of proteins.
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 substance on the plasma membrane helps identify chemical signals from outside the cell?
carbohydrates
Which of the following types of membrane proteins are responsible for facilitated diffusion?
Channel proteins and carrier proteins are responsible for facilitated diffusion. Channel proteins form hydrophilic channels that allow specific ions or molecules to pass through the membrane, while carrier proteins undergo conformational changes to transport molecules across the membrane.
