Question

Is ATP utilized in transport of glucose?

Answer 1

Glucose transport:

1. There are two processes by which glucose is transported across the cell membrane.
2. Within the renal proximal tubule and intestine, transport of glucose takes place against a concentration gradient which is facilitated by a secondary active transport pathway.
3. In this pathway, glucose is co-transported with sodium ions.
4. In other cells, the transport of glucose takes place with the help of members of the GLUT family of active transporters.
5. Glucose is also transported by sodium-glucose-linked transport (SGLT).
6. These transport mechanisms do not require ATP (Adenosine triphosphate) directly for transport.
