What molecule uses energy to push molecules through the membrane of a cell?
Transport Protein
The process by which glucose can pass through a cell membrane by combining with special carrier molecules is called?
Facilitated diffusion is the process by which glucose can pass through a cell membrane by combining with special carrier molecules.
What is the process called when molecules must join with another molecule such as a protein to get through a membrane?
facilitated diffusion
What type of molecules can permeate the plasma membrane?
Any molecule smaller than the holes in the membrane can pass through is the membrane is permeable. If the membrane is semi-permeable, then only molecules that the membrane selects can pass through. Electronegativity and existence of lipid layers are common selective traits for semi-permeable membranes.
What are the properties of solutes that can cross a membrane by simple diffusion?
The size of the molecule. Usually if a membrane is semi - permeable (only allows some molecules through by simple diffusion) the molecule that will be allowed through most is H2O(water).
What molecule uses energy to push molecules through the membrane of a cell?
Transport Protein
Molecules A and B come in contact with the cell membrane of the same cell Molecule A passes through the cell membrane readilybut molecule B does not Which statement could describe molecules A an?
molecule A is a SImple Sugar WHile B Is Starch
The process by which glucose can pass through a cell membrane by combining with special carrier molecules is called?
Facilitated diffusion is the process by which glucose can pass through a cell membrane by combining with special carrier molecules.
What kind of molecules can easily pass through a cell membrane?
Small, Non-polar molecules. If the molecule is polar, it sticks to both sides of the membrane, and has to go through selective routes. The easiest to get through is the Non-polar (oxygen and carbon).
What is a diffused molecule from a semipermeable membrane?
What is the situation? Provided a concentration gradient and a molecule that passes through a membrane, diffusion will happen. Generally small and nonpolar molecules will pass through a membrane down a concentration gradient. That doesn't answer your question but it may be the answer your looking for.
What is the process called when molecules must join with another molecule such as a protein to get through a membrane?
facilitated diffusion
Molecules A and B are both organic molecules found in many cells when tested it is found that molecule A cannot pass through a cell membrane but molecule B easily passes through state one way the two?
The molecules differ in size. B must be smaller than A because it can diffuse through the semipermeable cell membrane.

Electronegativity and existence of lipid layers are common selective traits for semi-permeable membranes.
Can all molecules diffuse through all cell membranes?
No, there are specific cell membranes that allow only certain molecules to pass through. Some stay open and others must be opened ( like a gate ).
Assisted transport of a molecule across the cell membrane without an expenditure of energy is known as?
Any movement of molecules into or out of a cell without the expenditure of energy is called diffusion. If the molecule uses special channels to diffuse through the membrane (again, not expending energy), it is called facilitated diffusion.
How do cells transport molecules across a cell membrane?
Molecules can move through the membrane in many ways. If the molecule is hydrophobic (or lipophilic) it can easily pass through the membrane. Other than that, most molecules move through the membrane through channels (which flow towards the molecules concentration gradient) or pumps (which flow against a molecules concentration gradient using energy).
