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.
611, Clinton was impeached on December 19, 1998, by the House of Representatives on grounds of perjury to a grand jury (by a 228â206 vote) and obstruction of justice (by a 221â212 vote).hortly after the elections, Gingrich, who had been one of the leading advocates for impeachment, announced he would resign from Congress as soon as he was able to find somebody to fill his vacant seat; Gingrich fulfilled this pledge and officially resigned from Congress on January 3, 1999.
