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 else can I help you with?
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.
What used a protein to move a molecule across a cell membrane without energy?
Facilitated diffusion uses proteins to move a molecule across the cell membrane without energy.
A special molecule that uses energy to push molecules through a membrane of a cell is called?
The special molecule is called ATP, which stands for adenosine triphosphate. ATP provides the necessary energy to power transport proteins in the cell membrane to move molecules across it.
Mitochondria uses which molecule to store energy?
The molecule produced by the mitochondria is the energy-carrier molecule. It's name is adenosine triphosphate, or ATP for short.
Which process is the first step in making a protein from DNA instruction?
The first step in making a protein from DNA instructions is transcription. During transcription, a specific segment of DNA is copied into a molecule of messenger RNA (mRNA) by an enzyme called RNA polymerase. This mRNA molecule then carries the genetic information from the DNA to the ribosomes for translation.
Which process uses the code on an RNA molecule to make a protein?
homozygous and heterozygoues
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.
How do you uses macromolecule in a sentence?
A macromolecule is just a molecule with a large number of atoms. A protein is an example of a macromolecule.
What uses channel proteins to help it across the cell membranes?
Water is one specific molecule. Its channel proteins are called aquaporins.
What uses a protein to move a molecule across a cell membrane without using energy?
Facilitated diffusion uses proteins to move a molecule across the cell membrane without energy.
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.
How much protein does a brownie have?
A brownie's protein content is entirely dependent on the ingredients used. For example, a brownie recipe that uses a lot of eggs will have more resulting protein.
What is an example of channel of distribution?
Name a company that uses conventional distribution channels to sell their products
What is an example of a conventional distribution channel?
Name a company that uses conventional distribution channels to sell their products
What used a protein to move a molecule across a cell membrane without energy?
Facilitated diffusion uses proteins to move a molecule across the cell membrane without energy.
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)
