Answer: A(secondary active transport)
Explanation:
Secondary active transport, is transport of molecules across the cell membrane which utilizes energy created by co-transporter pumping of ions across the membrane in an electrochemical gradient.
The reabsorption of glucose from the proximal tubule occurs via secondary active transport.
The reabsorbption of glucose does not depend the concentration gradient but on the reabsorption of sodium a co-transporter.
ATP is used in the movements of Na+/K+. Energy is also produced from sodium electrochemical gradient concentration and it is enough energy to transport glucose across the membrane into the epithelial cells.
