Describe the three parts of an ATP molecule.


Adenosine triphosphate (ATP) is a chemical compound which serves as the chemical fuel of living organisms. ATP is composed of adenine, ribose, and 3 phosphate groups. At the center of the ATP is the sugar molecule called ribose. There is an adenine attached to one side of the ribose, while the 3 phosphate groups are linked on the other side. In plant cells, ATP is produced in mitochondria and chloroplasts. It is the energy source of a plant cell in doing its metabolic activities and photosynthesis.
