Please answer

1. All of the following are true about glucose recovery from the tubule fluid, except (choose the incorrect statement):

A- The CD recovers any glucose that is not reabsorbed by the PCT, nephron loop, and DCT B- Glucose recovery is made possible by low intracellular Na+ concentrations created by the NaK pump. C- All filtered glucose is reabsorbed in the PCT unless plasma glucose is abnormally high D- It is reabsorbed by coupling with Na+ recovery via a sodium-glucose cotransporter, SGLT

2. The main function of the nephron loop is to:

A- Recover glucose and salt from the tubule fluid B- Create a high osmotic concentration in the extracellular fluid of the renal medulla allowing water recovery by the CD C- Secrete drugs such as penicillin, and toxins D- Eliminate acid

3. Aldosterone acts on this region of the kidney

A- B- DCT C- afferent and efferent arterioles D- glomerulus
