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).
ATP is at a high level of chemical potential but the type of energy released from its hydrolysis depends on the application. The short answer is that the hydrolysis of ATP to ADP always releases heat, and if coupled with a cellular process it additionally produces either chemical potential (in another species) or work. Let me back up a bit, and note that ATP is a species that has a high degree of potential energy.
