Which of the following is true for excretion in humans?

Options

AGlucose and amino acids are reabsorbed in PCT by simple diffusion.
BDCT is impermeable to water.
COn an average, $25-30 \mathrm{gm}$ of urea is excreted out per day
DMaximum reabsorption occurs in the loop of Henle.

Correct answer

C. On an average, $25-30 \mathrm{gm}$ of urea is excreted out per day

Step-by-step solution

Glucose and amino acids are reabsorbed in PCT by secondary active transport. Water, sodium and chloride ions are reabsorbed in DCT. It is permeable to water. Maximum reabsorption takes place within the PCT. Humans are ureotelic and excrete out 25-30 gm of urea per day.
