What is the process in which certain molecules act as carriers to move materials such as sugar across the cell membrane?

Ions such as sodium, potassium, chloride and calcium. Some molecules that are too big to get through the lipid bilayer by themselves can also be shuttled across the membrane by carrier proteins.

What properties does a selective permeable membrane have?
the ability to allow materials to cross a membrane
What of a cell allows material to enter and exit the cell?
Which statements describe the cell membrane? Check all that apply. It only allows certain materials to leave the cell. It allows all materials to leave the cell. It only allows certain materials to enter the cell. It allows all materials to enter the cell. It helps the cell get rid of waste. It brings waste into the cell for storage.
What characteristic does it called when the cell membrane allows only certain molecules and ions to enter or exit the cell?
A "semi permeable" membrane.
What term is used to describe how the cell selects what materials enter and leave the cell?
selectively permeable or differentially permeable membrane
What is a semi-permeable material that controls the movement of materials in and out of a cell?
The semi-permeable part of the cell would be the cell membrane, which allows some molecules (water, in particular) to pass freely through but restricts the movement of other molecules (such as proteins and enzymes).
What is a thin sheet of materials that selectively aloows certain molecules to cross but prevents others from crossing?
Semi-permeable membrane
What is a membrane that only allows certain materials to pass through?
A membrane that permits the passage of only certain molecules is called a semi-permeable membrane. In its simplest form, this separation process is based on molecular size. Smaller molecules pass through and larger ones are retained. In most biochemical processes, a concentration gradient drives the movement of molecules through the membrane.
What properties does a selective permeable membrane have?
the ability to allow materials to cross a membrane
What is the plasma membrane function that keeps materials outside the cell from going inside?
The characteristic that a plasma membrane bears is the semi-permeability. This is what keeps certain materials in while keeping certain materials out.
What do you call a cell membrane that allows certain molecules to pass through?
A selectively permeable membrane.
What does it mean if a cell membrane is selectively permiable?
The cell membrane only allows certain molecules through.
What is a semipermeable mebrane?
The cell membrane is called as semi-permeable membrane because it allows only certain/selective molecules to pass through it.It mostly allows only solvent molecules to pass.It is sometimes also called as selectively permeable membrane.
Why do you think that the eggs membrane will let water to enter but not corn syrup?
water molecules are smaller than corn syrup. the membrane allows a certain size of molecules.
What of a cell allows material to enter and exit the cell?
Which statements describe the cell membrane? Check all that apply. It only allows certain materials to leave the cell. It allows all materials to leave the cell. It only allows certain materials to enter the cell. It allows all materials to enter the cell. It helps the cell get rid of waste. It brings waste into the cell for storage.
What allows certain materials to enter and exit the plant cell?
The cell membrane
What only certain materials can enter the cell?
because of the semi - permeable membrane.
What allows certain substances to pass into and out of the nucleus of the cell?
Nuclear membrane
