When Mass begins, the Chalice is covered by the folded purificator and the pall (see below). Paten. The consecrated gold or gilded silver plate on which the Sacred Host is laid. Only priests or deacons are allowed to touch the Paten (though sacristans may in the course of their duties). A Communion Paten has a handle and is held under the chin of one receiving the Eucharist so that in case the Host is dropped, it won't fall to the floor.
1 Cells require a constant supply of energy to survive, but cannot store this energy as free energy as this would result in elevated temperatures and would destroy the cell. 2  Cells store energy in the form of adenosine triphosphate, or ATP.  Energy is released when the terminal phosphate group is removed from ATP.
Energy is usually liberated from the ATP molecule to do work in the cell by a reaction that removes one of the phosphate-oxygen groups, leaving adenosine diphosphate (ADP). When the ATP converts to ADP, the ATP is said to be spent.hosphates are well-known high-energy molecules, meaning that comparatively high levels of energy are released when the phosphate groups are removed. Actually, the high energy content is not the result of simply the phosphate bond but the total interaction of all the atoms within the ATP molecule.
