Glucose is usually reabsorbed from the filtrate in the kidney back into the blood through carrier proteins, hence, glucose in the urine is considered abnormal. What condition below might result in glucose in the urine?
A) high levels of glucose in the blood.
B) transport maximum for renal glucose reached.
C) excess consumption of glucose.
D) competitors for glucose carriers.
E) all of these answers.

All of the listed conditions can result in glucose in the urine. A) High levels of glucose in the blood can exceed the transport maximum for renal glucose reabsorption resulting in the presence of glucose in the urine. B) If the transport maximum for renal glucose reabsorption is reached, excess glucose in the filtrate cannot be reabsorbed and will be excreted in the urine. C) Excess consumption of glucose can result in high levels of glucose in the blood, which can exceed the transport maximum for renal glucose reabsorption. D) Competitors for glucose carriers can block glucose reabsorption and result in glucose in the urine.
