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.
ATP can be used to store energy for future reactions or be withdrawn to pay for reactions when energy is required by the cell. Animals store the energy obtained from the breakdown of food as ATP. Likewise, plants capture and store the energy they derive from light during photosynthesis in ATP molecules.ATP is a nucleotide consisting of an adenine base attached to a ribose sugar, which is attached to three phosphate groups.hen one phosphate group is removed by breaking a phosphoanhydride bond in a process called hydrolysis, energy is released, and ATP is converted to adenosine diphosphate (ADP). Likewise, energy is also released when a phosphate is removed from ADP to form adenosine monophosphate (AMP).
