Predict what would happen if the proximal convoluted tubule of the nephron lost its ability to reabsorb materials. A)The volume of the urine would increase dramatically. B)Nitrogenous wastes would accumulate dramatically in the blood. C)K⁺ ions,Na⁺ ions,and HCO₃^- ions would be lost unnecessarily. D)Glucose would lost unnecessarily. E)Glucose,K⁺ ions,Na⁺ ions,and HCO₃^- ions would be lost unnecessarily.

Question

Quizplus · Accepted Answer

The proximal convoluted tubule is responsible for reabsorbing many important substances, including glucose, K⁺ ions, Na⁺ ions, and HCO₃^- ions. If it lost its ability to reabsorb these materials, they would all be lost unnecessarily in urine. This would lead to significant glucose loss, as well as an imbalance in important ions and potentially lead to metabolic disturbances. Thus, choice E is the correct answer.
