All the glucose in the filtrate is normally reabsorbed in the
Correct answer: A. proximal convoluted tubule
- A. proximal convoluted tubule
- B. collecting duct
- C. loop of Henle
- D. Bowman's capsule
Explanation
The proximal tubule cells carry microvilli and many mitochondria because glucose and amino acids are recovered here by active transport, along with most of the water and salts. Reabsorption is described as selective because useful substances are taken back while urea is largely left behind. The collecting duct handles the final water adjustment under the control of ADH, not glucose recovery.

About Kidney and Urinary System
The kidney and urinary system remove nitrogenous wastes, regulate water and ion balance, and help maintain blood pH through filtration, selective reabsorption and secretion. Questions cover nephron structure, ultrafiltration, the loop of Henle, collecting ducts, urine formation and the roles of ADH and aldosterone, while distinguishing excretion from egestion.
