Cellular energy refers to the various processes and mechanisms by which cells obtain and utilize energy to carry out their essential functions and maintain viability. Cells require energy for various purposes, including biosynthesis, active transport, cell division, and other metabolic activities. The primary sources of cellular energy are adenosine triphosphate (ATP) molecules, which are generated through different metabolic pathways.
Thus, it seems logical that proteins sensing cellular energy status should monitor either the ADP/ATP or AMP/ATP ratio, or both
This means that any rise in the ADP/ATP ratio, which signifies falling energy status, causes the adenylate kinase reaction to be displaced towards ATP and AMP production
