An example of a molecule that uses a channel protein is glucose. Glucose transporters, specifically GLUT proteins, facilitate the passive transport of glucose across the cell membrane through channel proteins, allowing cells to absorb glucose efficiently without the need for energy. This process is crucial for maintaining energy levels in cells, particularly in insulin-sensitive tissues like muscle and fat.

What molecule does a protein pump use for energy?

A protein pump, such as the sodium-potassium pump in cells, uses ATP (adenosine triphosphate) as the molecule for energy. ATP provides the necessary energy for the pump to actively transport ions across the cell membrane.


How does faciliated diffusion work?

Facilitated diffusion is the process in which a membrane protein helps (facilitates) a substance pass through the bilayer. For example, water is too big a molecule to passively diffuse through the phospholipid bilayer and does not need to be actively imported. So the solution to this, is to put a transmembrane protein in the bilayer to form a channel big enough for the water molecule to pass through. I don't know how much you need to know, but just as a side note, the channel protein will be in its secondary structure, either as a beta sheet or alpha helix. I hope that helps.

What are the passive transport?

Passive transport processes do not require ATP or energy for transport. Co-transport processes would also not be considered a passive process. -The xylem in plants uses capillary action, a passive process -If a specific channel exists for, let's say, an ion or molecule, then that channel uses passive transport, however, it the channel cannot be "gated" in any way as in voltage-gated Na+ channels or delayed rectifier K+ channels. You can also look at the ascending loop of Henle in the juxtamedullary nephron of the kidney and see passive transport of water molecules -The blood brain barrier also allows passive transport of certain molecules A good way to think of passive transport is whether or not the plasma membrane has "holes" big enough in it to allow for molecules to pass through, provided there are no charge hindrances for that molecule passing through. Or a specific channel is open and letting a molecule in without the expense of ATP (using ATP to make the membrane channel protein does not fall under this category)
