3. Describe how active transport functions in the context of glucose reabsorption in
the kidney nephron.
Active transport moves glucose against its concentration gradient from the
proximal tubule back into the tissue fluid.
Active transport allows glucose to move freely along its concentration gradient
into the urine.

nephron.
, Active transport is the process by which glucose is filtered from the blood into
the Bowman's capsule.
