Which protein is responsible for transport of glucose across cell membrane?
A family of proteins called GLUT carry glucose molecules across the cell membrane.
What is a molecule used by glucose as a piggyback into and out of the cell in the process of active transport?
The glucose transporter is a membrane bound protein that binds to glucose and mediates it's transport into or out of the cell.
Facilitated is an example of what?
The glucose transporter that is activated by insulin (glut 4) is a prime example.
What facilitated diffusion an example of?
The glucose transporter that is activated by insulin (glut 4) is a prime example.
What is an example is facilitated diffusion?
The glucose transporter that is activated by insulin (glut 4) is a prime example.
How do sugar glucose molecules able to pass through the cell membrane?
facilitated diffusion - a solute binds to a specific transporter on one side of the membrane and is released on the other side after the transporter undergoes a conformational change. includes glucose,urea,fructose,galactose,and some vitamins.
What is Facilitated diffusion is an example of?
The glucose transporter that is activated by insulin (glut 4) is a prime example.
Where is GLUT4 found?
GLUT4 is the insulin-regulated glucose transporter found in adipose tissues and striated muscles (skeletal and cardiac) that is responsible for insulin-regulated glucose disposal."Allows equilibrium with blood-bidirectional".
How are glucose molecules moved into the cell and what transport is this?
The following Glucose transporter move glucose across the membrane along its concentration gradient, that is from the higher to the lower glucose concentration.1) Glucose Transporter GluT, for instance GluT1 are expressed in endothelial cells that line the blood vessels and that form the barrier between brain and blood. Small amount of GluT1 are also found in many other tissues.2) GluT2 appears in Organes that release glucose into the blood, such as liver, kidney, intestine, pancreas.3) GluT3 are found in the neuronal cells of the brain. The reason is that GluT3 has higher affinity to glucose than GluT1.4) GluT4 are found in musle and fat cells.5) GluT5 found in small intestine and kidney.Another familly is called cotransporter (sodium-glucose linked transporter, SGLT) it pulls glucose against the gradient, it couples the transport of a glucose with a sodium ion. The enrgy comes from th sodium ion own mouvement along its own gradient.
How insulin signals a cell to take in glucose from the blood?
The insulin binds to insulin receptors on the surface of muscle or liver cells. This opens up little holes in the cell membrane called glucose transporters. Glucose flows through the glucose transporter due to the concentration gradient of glucose being higher in the extracellular environment. This is called diffusion. The membrane only stays permeable (open) to glucose so long as there is insulin bound to the receptors on the cell surface. Eventually the insulin is released and the glucose transporter closes. The cell then starts to digest the glucose via complicated processes called glycolysis and oxidative phosphorylation.
What is the age on transporter DVD?
transporter is an 18
What is the duration of The Transporter?
The duration of The Transporter is 1.53 hours.
