Reabsorption of Filtered Glucose from the Lumen in the PCT

Question

Reabsorption of filtered glucose from the lumen in the PCT is largely by means of
A) diffusion.
B) facilitated diffusion.
C) active transport.
D) cotransport.
E) countertransport.

Accepted Answer

The reabsorption of filtered glucose from the lumen in the PCT is largely by means of cotransport, which involves moving glucose across the membrane along with sodium ions, utilizing the energy from their electrochemical gradient. This process is also known as secondary active transport.
