Sometimes particles can pass through a membrane with little trouble such as water. For other, bigger particles, proteins act as a specific receptor for the particles to attach to. If the particle attaches to the receptor properly (imagine a lock and key metaphor) the protein will pull the particle into (or out of) the cell.
This is how if you have a headache and take medicine for it, the medicine will target the brain. The drug will flow all through your body skipping over the cells in your legs for example because only the proteins needed are in your head.
What else can I help you with?
What membrane components allow movement of non-polar substances across membrane?
Integral proteins allow movement of non-polar substances across membranes.
What are the special structures in the cell membrane that allow materials such as water and sugar to pass through made o?
The special structures in the cell membrane that allow materials like water and sugar to pass through are proteins called transport proteins. These proteins help facilitate the movement of specific molecules across the membrane by acting as channels or carriers. They play a crucial role in regulating the flow of substances in and out of the cell.
What kind of protein helps some substances cross the cell membrane?
Carrier proteins help facilitate the movement of certain substances across the cell membrane by binding to specific molecules and carrying them across. These proteins undergo conformational changes to transport the substances across the membrane.
What helps to allow materials to cross the plasma membrane?
Materials cross the plasma membrane through processes such as simple diffusion, facilitated diffusion, and active transport. These processes involve the movement of substances across the lipid bilayer of the membrane with the help of transport proteins or by utilizing energy to move against a concentration gradient.
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.
What must be used to transport materials that cannot diffuse across the membrane?
Transport proteins, such as channels and carriers, must be used to transport materials that cannot diffuse across the membrane. These proteins facilitate the movement of specific substances across the cell membrane by providing a passageway or binding site for the molecules to move through.

The resistance to an ion's movement across a membrane is determined by?
The resistance to an ion's movement across a membrane is primarily determined by the membrane's permeability to that specific ion. Factors such as ion channel proteins, membrane potential, and concentration gradients also play a role in regulating ion movement.
How is the movement of materials across the cell membrane related to the survival of the organism?
its your mama :p
What is the movement of materials across a cell membrane without using energy?
This type of movement is called simple diffusion.
What is the process that utilizes a carrier to move materials across the plasma membrane in the direction of the concentration gradient that does not use ATP?
Active Transport
What role do membrane transport proteins, such as channels, carrier proteins, and pumps, play in the movement of substances across cell membranes?
Membrane transport proteins, like channels, carrier proteins, and pumps, help regulate the movement of substances across cell membranes. Channels allow specific molecules to pass through, carrier proteins transport molecules across the membrane, and pumps use energy to move molecules against their concentration gradient. These proteins are essential for maintaining the balance of substances inside and outside the cell.
