The absorption of glucose takes place as a result of the formation of urine in the kidney as a part of the nephron physiology. The absorption of glucose is important to the body as the loss of glucose with urine will cause disease.
The glucose is absorbed in the proximal convoluted tubule of the nephron where the cotransporter channel called SGLT2 is embedded in the membrane. The SGLT2 symports the sodium along with the glucose where transport of sodium ions drives the process of reabsorption.
