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.
Jack Tormoehlen Cells use ATP for energy. The energy comes from releasing a phosphate group from ATP to create ADP. This energy is used throughout the Cell for various functions. ATP contains a purine base, adenine, a sugar, ribose, and three phosphate groups. The adenine and ribose combine to make adenosine.TP is produced in many ways. Fermentation, respiration and photosynthesis are the main ways. Cells use ADP (Adenosine di-phosphate) and add a phosphate group. After ATP is broken down into ADP and a phosphate group, the parts recycle to form ATP again.
