Cells lining a kidney tubule reabsorb glucose into the blood. The glucose concentration in the tubule fluid is lower than in the blood. A chemical reduces the rate of respiration in these cells. Which statement describes the effect of the chemical on glucose reabsorption and its consequence?
Less energy is available for active transport, so less glucose is reabsorbed and more may be lost in the urine
Reabsorption is unchanged because active transport uses the kinetic energy of glucose particles
Less glucose is used by the tubule cells, so more glucose is reabsorbed and less is lost in the urine
Less energy is available for diffusion, so less glucose is reabsorbed and more may be lost in the urine
