Facilitated diffusion moves large molecules through what?
Glucose and polypeptides.
How would you define diffusion?
Cellular diffusion is when molecules in the cell go from high concentration to low concentration to balance out the concentration. Small molecules can diffuse through the cell membrane, but larger molecules need the help of proteins. This is call facilitated diffusion.

Is Diffusion made of small or large molecules?
Diffusion is not a substance. It is a physical process. Diffusion is the process where there is a movement of molecules from where they are abundant to where they are scarce. A more technical definition would be: Diffusion is a process in which molecules move from a region of higher concentration to a region of lower concentration.
What is the difference between simple diffusion and facilitated diffusion?
It doesn't. (answer by RRU member Cyrem)
Is diffusion better in a solid or a gas?
What kind of diffusion? If it is diffusion of molecules then gas would be the right platform
How does faciliated diffusion differ from simple diffusion?
Facilitated diffusion needs some sort of help. Often it would be a protein. Simple diffusion doesn't. If you spill something smelly on the floor in the kitchen, you will smell it all through the house. It will spread by simple diffusion.
What state does diffusion eventually lead to?
Well if the diffusion is not interrupted by other influences it would be equilibrium because the concentration of molecules will be the same throughout the space the molecules occupy.
Diffusion of nonpolar molecules would not be affected by?
Diffusion of nonpolar molecules would not be affected by charge. Allosteric inhibition is generally a result of binding regulatory molecule at a site other than the active site.
What conditions would cause net glucose to be transported into a cell via facilitated diffusion Assume ATP is present inside the cell?
0.5m
What the role of protein channels in the cell membrane?
Protein channels are important to facilitate the transport of ions and other larger molecules across the plasma membrane. Large molecules cannot just diffuse thorough the membrane. In addition, polar molecules cannot diffuse through the membrane since it would be energetically unfavorable for them to negotiate the hydrophobic interior of the plasma membrane. Therefore, protein channels are essential in membrane transport.
What would be least affected by defective receptor proteins on a cell membrane a homeostasis b muscle activity c nerve signals d diffusion?
i think the answer is nerve signals because it is definitely not diffusion, because of facilitated diffusion blah blah blah
