Monstrance is the vessel used in the Church to display the consecrated Eucharistic Host, during Eucharistic adoration or benediction. The word monstrance comes from the Latin word monstrare, meaning to expose. It is known in Latin as an Ostensorium.
ATP hydrolysis. ATP hydrolysis is the reaction by which chemical energy that has been stored in the high-energy phosphoanhydride bonds in adenosine triphosphate (ATP) is released, for example in muscles, by producing work in the form of mechanical energy. The product is adenosine diphosphate (ADP) and an inorganic phosphate, orthophosphate (Pi).
Thus, ATP is the higher energy form (the recharged battery) while ADP is the lower energy form (the used battery). When the terminal (third) phosphate is cut loose, ATP becomes ADP (Adenosine diphosphate; di= two), and the stored energy is released for some biological process to utilize.
