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.
Through the nephron tubule and nutrients are recovered by being reabsorbed from the filtrate into the blood capillaries that surround the tubule. Furthermore,some chemicals mighht be actively secreted from those blood capillaries directly into the filtrate in the tubule.hrough the nephron tubule and nutrients are recovered by being reabsorbed from the filtrate into the blood capillaries that surround the tubule.
