Based on this information, what type of transport is used for glucose in blood and intestinal cells?


What type of transport is involved in this process?

Respuesta :

Glucose is transported across the apical plasma membrane (from the lumen inside the cell) of the intestine via the sodium-glucose cotransporter (Na/glucose cotransporter)- The gradient of the Na is established by the Na+/K+-ATPase.  This means that the absorption of the glucose is secondary active transport. Glucose is then transported into the extracellular fluid via the glucose transporter and that is the process of facilitated diffusion (passive process, since glucose flows down its concentration gradient).
