Question:

Which of the following is almost completely reabsorbed by active reabsorption in the nephrons of a healthy person?

Options:

1. Urea
2. Creatinine
3. Glucose
4. Water

Solution:

In a healthy person, glucose is almost completely reabsorbed by active reabsorption in the proximal convoluted tubule of the nephron. Glucose is transported into the cells lining the tubule by sodium-glucose cotransporters, and then it is transported out of the cells and into the peritubular capillaries by glucose transporters. Urea is partially reabsorbed and partially secreted in the nephron. Creatinine is not reabsorbed but is freely filtered at the glomerulus and then excreted in the urine. Water is reabsorbed by both passive and active transport mechanisms depending on the body's need for water conservation.
