14. Valuable molecules like glucose, amino acids, and vitamins are reabsorbed into the blood at which location in the nephron?

A. Loop of Henle

B. Bowman's capsule

C. proximal convoluted tubule

D. collecting duct

E. glomerulus

Answer: Option C.

Proximal convoluted tubule.

Explanation:

Renal reabsorption is the process molecules like glucose, amino acids, vitamins are reabsorbed from urine preventing them from being loss from the body) (urine) into the circulating blood. Once they are in the convoluted tubule, the molecules diffuse into the blood capillaries. This take place in the nephron.

Answer: Option C) proximal convoluted tubule

Explanation:

The nephron has the proximal tubule where some water, amino acids and salts which are useful to the body are reabsorbed into the blood capillaries against concentration gradient by active transport.

Thus, the process of selective reabsorbtion takes place in the proximal convoluted tubule
