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 facilitated transport?
Facilitated diffusion (or facilitated transport) is a process of diffusion, a form of passive transport facilitated by transport proteins. Facilitated diffusion is the spontaneous passage of molecules or ions across a biological membrane passing through specific transmembrane transport proteins. The facilitated diffusion may occur either across biological membranes or through aqueous compartments of an organism.
What is the process called when molecules must join with another molecule such as a protein to get through a membrane?
facilitated diffusion
What is the process When proteins help molecules move across the membrane is called?
when proteins help molecules move across the membrane, it it called Facilitated Diffusion
What process do sugar molecules enter or exit a cell?
1. Sugar (sucrose) cannot penetrate the cells and cannot be absorbed in blood because this disaccharide molecule is too big. 2. After the degradation of the disaccharide to monosaccharides (fructose, glucose, etc.) with the help of the enzyme sucrase these monosaccharides are easily absorbed in blood. 3. The monosaccharides molecules can penetrate by diffusion.
What macromolecule is involved in facilitated diffusion?
Facilitated diffusion is the process of transporting ions and other chemicals into a cell. The macro molecule involved in this process are proteins.
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.
In what process are carrier proteins important?
Carrier proteins is important in facilitated diffusion. Facilitated diffusion transports molecules from one area of higher concentration on one side of the membrane to an area of lower concentration on the other side .Because the molecules are moving down their concentration gradient , facilitated diffusion is passive transport.

Facilitated diffusion sentence?
Facilitated diffusion is a type of diffusion specifically for larger molecules, to help them cross a selectively permeable membrane with the help of integral proteins that act as carriers. Facilitated diffusion is a passive process, i.e. it does not need energy/ATP.
Compare and contrast active transport and facilitated diffusion-?
Active transport moves solutes against their concentration gradient; facilitated diffusion moves substances down their concentration gradient.
What is the process When proteins help molecules move across the membrane is called?
when proteins help molecules move across the membrane, it it called Facilitated Diffusion
What process is used to move sugar molecules across a cell membrane?
I do believe that the answer is facilated diffusion.
What process do sugar molecules enter or exit a cell?
1. Sugar (sucrose) cannot penetrate the cells and cannot be absorbed in blood because this disaccharide molecule is too big. 2. After the degradation of the disaccharide to monosaccharides (fructose, glucose, etc.) with the help of the enzyme sucrase these monosaccharides are easily absorbed in blood. 3. The monosaccharides molecules can penetrate by diffusion.
In facilitated diffusion which process does not require energy?
Simple and facilitated diffusion are a part of passive transport. This refers to the movement of molecules, atoms and ions across the cell membrane. In both of these processes, molecules move from areas of high concentration to areas of lower concentration because equilibrium is trying to be maintained in living organisms. Simple diffusion just happens randomly and without any aides. Facilitated diffusion uses proteins in the cell membrane to guide polar molecules and ions in and out of the membrane (always to areas of lower concentration) and DOES NOT require ENERGY.Only active diffusion requires energy.
What is facilited diffusion?
Facilitated Diffusion is the movement of molecules across cell membranes through protein channels and carrier proteins.Facilitated diffusion is a passive transport process, aka no energy required, where substances move down their concentration gradient (high concentration to low concentration) across a protein through a membrane protein because it is unable to diffuse directly through the phospholipid portion of the membrane itself.Diffusion of molecules assisted by protein channels that pierce a cell membrane
