Transport proteins allow charged molecules to pass through the cell membrane. The process of facilitated diffusion, a type of passive transport, allows transport proteins to take charges molecules into the cell.

What is meant by cell membrane is semipermeable?
It allows only certain molecules to pass through.
When a protein channel allows molecules to cross through the cell membrane?
when a protein channel allows molecules to cross through the cell membrane this is called facilitated diffusion. many might mistake this for diffusion which is the process by which molecules tend to move from an area where they are more concentrated to an area where they are less concentrated.
Molecules can pass through the cell membrane of the human cell?
The molecules that can pass through the cell membrane of the human cell include water. Other molecules include fat soluble vitamins.
What does selective permeability mean what is responsible for the selective permeability of the plasma or cell membrane?
When a cell's membrane is permeable, it means that only certain proteins and other molecules can go in and out of the porous membrane, through protein pumps and other pathways. Some molecules stay inside the cell, while others float outside. Starches, for example, are large molecules that cannot pass through the membrane.
What types of molecules can easily go through your cell membrane are permeable to the cell membrane?
Substances with a hydrophillic-lipophillic balance are permeable through the cell membrane.
What part of the cell membrane allows small molecules to pass through?
the cell membrane
What does it mean if a cell membrane is selectively permiable?
The cell membrane only allows certain molecules through.
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 is selectively permiable?
The cell membrane only allows certain molecules through.
What is meant by cell membrane is semipermeable?
It allows only certain molecules to pass through.
Can steriods and cholesterol cross the cell membrane on their own?
Yes because the cell membrane allows non polar molecules through
Which part of a cell allows substances to pass through it?
The cell membrane, which encloses the cell, is a selective membrane which allows some molecules to pass and others not.
How do small molecules get through the cell membrane against a concentration?
How do small molecules get through a cell membrane
Cell membrane is semipermeable what doe that mean?
It allows only certain molecules to pass through.
What is membrane permeability?
Membrane permeability refers to the ability of molecules, substances, etc. to pass through the membrane. For example, the cell membrane is referred to as 'semi-permeable' because it allows some molecules (such as water) to enter, and stops other molecules (such as sodium ions) from passing through the membrane. If these want to get into the cell, they must then rely on proteins in the cell membrane to let them in.
When a protein channel allows molecules to cross through the cell membrane?
when a protein channel allows molecules to cross through the cell membrane this is called facilitated diffusion. many might mistake this for diffusion which is the process by which molecules tend to move from an area where they are more concentrated to an area where they are less concentrated.
Is the cell membrane semi-permeable?
well no its the thin outer layer of the cell i beleive.
