A family of proteins called GLUT carry glucose molecules across the cell membrane.
Glucose is primarily absorbed into the blood through the intestinal epithelial cells lining the small intestine. This process occurs mainly in the jejunum, where glucose is transported across the cell membrane via specific transporters, such as SGLT1 (sodium-glucose co-transporter 1). Once inside the epithelial cells, glucose is then released into the bloodstream through facilitated diffusion via GLUT2 transporters.
Sodium fluoride can be used as a preservative for blood samples (for the glucose determination) avoiding glycolysis.
high Na+ concentration in the extracellular fluid; high K+ concentration in the cytoplasm
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.
Reabsorption of filtered glucose from the lumen in the proximal convoluted tubule (PCT) is largely by means of the sodium-glucose cotransporter 2 (SGLT2). This transporter is responsible for actively transporting glucose and sodium from the renal tubule back into the bloodstream. The glucose is then further passively reabsorbed through the facilitative glucose transporter 1 (GLUT1) in the PCT cells.
i think this is because of sodium and glucose transporter the transmembrane protein allow sodium ions and glucose to enter the cell together in the same direction and its used to actively transport glucose out of the intestine and out of the kidney tubules back to blood so in case of diabetes sodium cant be reabsorbed in kidney tubules and go to urine and thus sodium level decrease in diabetic patient
Glucose is not made from sodium chloride.
Glucose can move via two ways: 1. With the Sodium/glucose pump. As sodium is diffusing back into the cell the glucose will attach itself (co-transport) as a symporter across the membrane. The sodium is going with the gradient and the glucose is moving against its gradient. Therefore, Indirect active transport via a symporter as a co-transporter. 2. By facillitated diffusion by attaching itself to a proten carrier glucose will move with the gradient into the cell. This means that glucose it the only molecule that can enter or leave a cell under two different transportation modes.
A family of proteins called GLUT carry glucose molecules across the cell membrane.
Glucose molecules are moved into the cell via facilitated diffusion using glucose transporters located on the cell membrane. These transporters bind to glucose molecules and move them into the cell, following the concentration gradient.
The reaction between glucose solution and sodium hydroxide is a chemical reaction that involves the hydrolysis of glucose molecules by the strong base (sodium hydroxide). This reaction results in the formation of sodium gluconate and water. The hydroxide ions from the sodium hydroxide cleave the glycosidic bonds in glucose molecules, leading to the breakdown of glucose into simpler compounds.

The glucose transporter that is activated by insulin (glut 4) is a prime example.
The glucose transporter is a membrane bound protein that binds to glucose and mediates it's transport into or out of the cell.
Glucose transport into muscle cells is primarily facilitated by the glucose transporter 4 (GLUT4) carrier protein. This transporter is insulin-responsive and plays a crucial role in regulating glucose uptake by muscle cells to meet energy demands during exercise and recovery.
