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.
The president may be removed from office and never allowed to hold a government position again if he is found guilty. Our 17th president, Andrew Johnson, was impeached while in office. Thirty-five senators found him guilty -- just one vote short of the two-thirds vote necessary to convict him. President Richard Nixon resigned from office rather than face impeachment charges in the Watergate scandal in 1974. President Bill Clinton became the second president to be impeached by the House in 1998. Later, the Senate found him not guilty.
