Not necessarily, although its symbol is the water carrier, Aquarius is an AIR sign.  The water in Aquarius is symbolic of knowledge, especially spiritual.  Swimming in water â¦ is using it for a different purpose to, e.g. carrying it in a container.
Autoregulation is a process within many biological systems, resulting from an internal adaptive mechanism that works to adjust (or mitigate) that system's response to stimuli. While most systems of the body show some degree of autoregulation, it is most clearly observed in the kidney, the heart, and the brain. Perfusion of these organs is essential for life, and through autoregulation the body can divert blood (and thus, oxygen) where it is most needed. 1 Cerebral autoregulation.
ATP and Coupled Reactions. Many reactions in cells are endothermic (require energy), such as protein synthesis. The energy comes from the breakdown of ATP (adenosine triphosphate); this process provides energy and so is exothermic. When the energy released by an exothermic reaction drives an endothermic reaction these two reactions are said to be a coupled reaction. What is ATP (Adenosine triphosphate)? The ATP Cycle. How do we get energy from ATP? How much energy do we get from one ATP molecule? Every time ATP is broken down into ADP, 31 kJ/mol of energy is released.
