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).
The high-energy bonds of ATP are actually rather unstable bonds. Because they are unstable, the energy of ATP is readily released when ATP is hydrolyzed in cellular reactions. Note that ATP is an energy-coupling agent and not a fuel. It is not a storehouse of energy set aside for some future need.
