Although glucose enters the renal tubule during the first step of urine formation, it is actively transported back into blood during this second step in urine formation

The correct answer will be- true

Explanation:

Glucose is absorbed by the tubules of the kidney while urine formation which if not absorbed will be lost along with the urine.

During the first step of the urine formation, the Glucose is absorbed by the  SGLT2 cotransporter which also symports the sodium along with glucose in the tubule.

This absorbed glucose is transported to the blood capillaries through passive diffusion to maintain them once in the tubule.

The glucose is absorbed so that no glucose is lost along with urine but again backflow to the blood capillaries to maintain the glucose level.

Thus, true is the correct answer.

activation of phospholipase c (plc) indirectly increases intracellular ions through inositol triphosphate (ip3).
