Water can move passively through a membrane by moving through the pores of a cell. Other substances cannot move through a cell membrane.

What uses a protein to move a molecule across a membrane without energy?

Facilitated diffusion uses proteins to move a molecule across the cell membrane without energy.


What cell membrane structure allows water-soluble materials to be passively transported to the cytoplasm?

Carrier proteinsProteins in the cell membrane that assist with facilitated diffusion are known as carrier proteins since they carry materials across the membrane. Carrier proteins bind to a molecule on one side of the membrane, change shapes to shield the molecule from the lipid bilayer, and then release the molecule on the other side of the membrane

What type of molecule can be used as a tunnel to move compounds across the cell membrane?

Carrier proteins are a type of molecule that can be used as a tunnel to move compounds across the cell membrane. These proteins bind to specific molecules and undergo conformational changes to transport them across the membrane. This process is known as facilitated diffusion.

In osmosis What molecule does not move across the membrane?

In osmosis, large molecules like proteins and polysaccharides do not move across the membrane. Only smaller molecules such as water and ions can pass through the membrane during osmosis.


The use of energy to move substances across a cell membrane describes?

Active transport, which requires energy in the form of ATP to move substances against their concentration gradient across a cell membrane. This process involves specific protein pumps that bind to the molecule being transported, consuming ATP to change conformation and move the molecule across the membrane.


Is diffusive equilibrium possible for the molecule that is impermeable?

No, diffusive equilibrium requires a concentration gradient and the ability of the molecule to pass through a membrane. If a molecule is impermeable, it cannot move freely across the membrane, so diffusive equilibrium is not possible for that molecule.
