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 is therefore continuously recycled in organisms: the human body, which on average contains only 250 grams (8.8 oz) of ATP, turns over its own body weight equivalent in ATP each day.
Mitochondria supply the cell with ATP (Adenosine Triphosphate), which is the energy the cell needs. A heart cell is a type of muscle cell which needs plenty of energy to con â¦ tract and keep functioning. This is why a heart cell needs more mitochondria than other cells-because they need more energy.
