WebInsulin works to decrease the concentration of glucose in the blood and facilitate transport into the cells by binding to special receptors embedded in their membranes. The binding of insulin to the cell leads to a rapid movement of the vesicles to the cell membrane, where they fuse with it and insert the glucose transporters. 00:00 00:00. WebThe glomeruli filter from plasma approximately 180 grams of D-glucose per day, all of which is reabsorbed through glucose transporter proteins that are present in cell membranes within the proximal tubules. If the capacity of these transporters is exceeded, glucose appears in the urine.
