ATP transports chemical energy within cells for metabolism. It is one of the end products of photophosphorylation, cellular respiration, and fermentation and used by enzymes and structural proteins in many cellular processes, including biosynthetic reactions, motility, and cell division.TP transports chemical energy within cells for metabolism.

Perhaps the most well known event that occurred recently on this day was in 1998 when President Clinton was impeached for lying to a grand jury about his affair with Monica Lewinski. All of this, along with more, is explained in the This Day in History Video: December 19th.
Impeachment is a formal process in which an official is accused of unlawful activity, the outcome of which, depending on the country, may include the removal of that official from office as well as criminal or civil punishment. Bill Clinton, Democrat, was impeached on December 19, 1998, by the House of Representatives on articles charging perjury (specifically, lying to a federal grand jury) by a 228â206 vote, and obstruction of justice by a 221â212 vote.
