Describe the mechanism for reabsorption of water, glucose and Na+ in the PCT.

Answer #1

Proximal convoluted tubule is a part of nephron, it reabsorbe water, glucose, Na+ and transport it into the bloodstream and this process is mainly isosmotic in nature. This reabsorption process occurs through paracellular path and transcellular path. Glucose passes along the basolateral membrane by facilitated diffusion. Na+ passed from the lumen to the blood, Ions present in the basolateral membrane, hepls in the reabsorbtion of Na+. Water is reabsorbed by osmosis, they often moved from renal tuble, mainly using paracellular path.

The Na –glucose symport system of intestinal epithelial cells couples the \"downhill\" transport of two Na ions into the cell to the \"uphill\" transport of glucose, pumping glucose into the cell against its concentration gradient. If the Na concentration outside the cell ([Na ]out) is 159 mM and that inside the cell ([Na ]in) is 23.0 mM, and the cell potential is -49.0 mV (inside negative), calculate the maximum ratio of [glucose]in to [glucose]out that could theoretically be produced if...
