Diarrhea is one of the most common causes. It can be caused by eating wrong kind of foods or by overeating. Consumption of contaminated food can lead to bacterial or viral infection in the stomach resulting in diarrhea and cramping of stomach.
Structural Biochemistry/ATP. Adenosine triphosphate (ATP) is a nucleotide that consists of an adenosine and a ribose linked to three sequential phosphoryl (-PO32-) groups via a phosphoester bond and two phosphoanhydride bonds. ATP is the most abundant nucleotide in the cell and the primary cellular energy currency in all life forms. The primary biological importance of ATP rests in the large amount of free energy released during its hydrolysis.
Because it is responsible for the transfer of energy from one set of biochemical reactions to another. Gtp and Utp are sometimes also used. Atp delivers energy wherever energy is needed in the Cell. Atp (Adenosine tri-phosphate) is a molecule that can store energy. The bond between the terminal phosphate and the second phosphate is a high-energy bond. When it is broken (Atp is turned into Adp and Pi) this energy is released and can be harnessed by the Cell.
