Combined Positron-Emission and Computed Tomography in the Study of the Kidneys Energy Metabolism
Biochemical reactions that provide the process of urine secretion and excretion are well studied, and they are based on the energy-dependent transmembrane movement of molecules on both sides of the nephron. This unique machine is designed in such a way that not only the physiological processes of its activity, but also pathological destructive reactions require the use of biological energy carriers. So a fast source of energy is a glucose molecule built into the membrane ATP-ASE, the long-term carrier of energy potential are lipids, or rather membrane phospholipids containing a molecule of choline. These energy “swings” are the essence of the entropy of living matter [1-6].
