Killer whales are marine mammals belonging to the family Delphinidae, formed by several species of dolphins, false killer whales and pilot whales.
Active transport is the key to the reabsorptive processes in the proximal tubule. Glucose and amino acids are reabsorbed across the apical membrane of the proximal tubule by sodium-coupled secondary active transport. Na + glucose transport is mediated by the low affinity, high capacity SGLUT2 transport protein.
How and where does most reabsorption occur in a nephron? The proximal tubule is the site of most reabsorption via glucose transporters (reabsorb 100% of glucose in healthy individuals), approx. 65% Sodium and various other solutes a â¦ re also reabsorbed.eabsorption in a nephron occurs in the Loop of Henle Reabsorption has been addressed to substances which are absorbed back from the nerphrone back in to the blood(capillaries â¦). On other hand Secretion is the absorption of substances from blood.
