Adenosine Triphosphate

A multifunctional nucleotide used in cells as a coenzyme; it is often called the "molecular unit of currency" of intracellular energy transfer:


Adenosine Triphosphate (ATP)

The ultimate source of energy for all plants and animals is sunlight. But the sun’s energy can be harnessed by plants, through photosynthesis, and stored in molecules of carbohydrates. When animals eat these nzymes, large amounts of energy become available. Animals immediately convert this energy into molecules of high-energy ATP (adenosine triphosphate) – the universal currency of energy in living things. Excluding only the very first stages in carbohydrate breakdown, which are called glycolysis, the entire complicated process of energy transfer to ATP takes place within the mitochondria.
