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.
What else can I help you with?
How are glucose molecules moved into a cell and what kind of transport is this?
Glucose molecules are moved into a cell via a transport protein called a glucose transporter. This process is facilitated diffusion, a type of passive transport that does not require energy. Glucose transporters help move glucose across the cell membrane down its concentration gradient.
What type of transport is it when gluclose molecules move into a cell?
Glucose molecules entering a cell typically occurs through facilitated diffusion, which is a type of passive transport. This process involves the movement of glucose across the cell membrane with the help of specific transporter proteins.
The cell uses energy to transport glucose through the cell membrane?
Glucose moves across the cell membrane through facilitated diffusion. This type of transport uses protein carriers to assist glucose molecules across the cell membrane from an area of high concentration to an area of low concentration.
What substance cannot be moved into a cell by osmosis or diffusion?
Large molecules such as proteins cannot be moved into a cell by osmosis or diffusion due to their size and charge. These molecules require specialized transport mechanisms such as active transport to enter the cell.
Some materials can move across the cell membrane against a concentration gradient by?
Large molecules such as glucose that cannot cross the phospholipid bilayer can still move across the membrane through transport proteins by active transport. Active transport uses energy to move molecules the bilayer.

There is a need for glucose inside a cell but the glucose molecule is too large to pass through the cell membrane How does the cell solve this problem?
The cell solves this problem by using transport proteins called glucose transporters. These transporters serve as gateways in the cell membrane, allowing glucose molecules to pass through into the cell. This process is facilitated by protein channels that specifically recognize and transport glucose molecules.
Why oxygen molecules do not across a cell membrane while glucose molecules do not?
Glucose is too big to pass throught.
How are glucose molecules moved into cell?
Glucose can move into cells by active or passive transport, in both cases membrane-spanning proteins are required. Active transport (SGLT) uses the concentration gradient of Sodium ions to move glucose against its concentration gradient. Passive transporters (GLUT) are only effective if the concentration of glucose in the cell is lower than outside the cell.
How are glucose molecules moved Ino a cell?
The glucose goes in through the membrane and can in or out either ways.
How does a cell keep glucose from escaping without breaking down the molecule?
Compared to other more basic molecules, glucose is rather large. In order for glucose to enter the cell in the first place, the cell must actively transport it from outside the cell wall using special transport proteins. This is compared to a cell passively transporting molecules, where the molecules are small enough (or non polar) to pass through the cell membrane without any action from the cell itself.Once the glucose is in the cell, there is no way to get out.
The cell uses energy to transport glucose through the cell membrane?
Glucose moves across the cell membrane through facilitated diffusion. This type of transport uses protein carriers to assist glucose molecules across the cell membrane from an area of high concentration to an area of low concentration.
Why do cells need carriers proteins that transport glucose?
Large molecules, such as glucose, are not able to pass through the cell membrane. Therefore proteins are needed to transport them across.
What substance cannot be moved into a cell by osmosis or diffusion?
Large molecules such as proteins cannot be moved into a cell by osmosis or diffusion due to their size and charge. These molecules require specialized transport mechanisms such as active transport to enter the cell.
How does active transport of glucose cause osmosis?
Osmosis is the transport of water across semi permeable plant membrane. When glucose molecules actively transport to the plant they lower the water potential of the plant and therefore water moves in to balance that. This is how active transport assists osmosis.
Some materials can move across the cell membrane against a concentration gradient by?
Large molecules such as glucose that cannot cross the phospholipid bilayer can still move across the membrane through transport proteins by active transport. Active transport uses energy to move molecules the bilayer.
