Question

Which nephron structure is primary site of glucose reabsorption?

RankGuru · Accepted Answer

1. **Nephron Function**: Filtration occurs in the glomerulus, followed by extensive reabsorption in the tubules.
2. **Proximal Convoluted Tubule (PCT)**: This is the most active site for reabsorption.
3. **Glucose Status**: In a healthy person, **$100\%$ of the filtered glucose** is reabsorbed back into the blood in the **PCT**.
4. **Mechanism**: This happens via secondary active transport using sodium-glucose co-transporters (SGLTs).
5. **Loop of Henle**: Primarily responsible for maintaining the osmotic gradient for water and salt balance.
