Cells are paired with the exergonic reactions to harness the energy within the bonds of ATP. Adenosine triphosphate comprises the nitrogenous base adenine, the fine carbon sugar ribose, and three phosphate groups. The energy distributed by the hydrolysis of ATP into ADP is used to execute cellular work, usually by combining the two's reactions.
In living things, glucose is the essential nutrient, but ATP is the basic fuel. ATP is a nucleotide, which involves five different nitrogenous bases, a five-carbon sugar called ribose, and one to three phosphate groups.
The TP in ATP stands for triphosphate and indicates that ATP has the maximum number of phosphate groups that a nucleotide can have. The attachment makes most ATP of a phosphate group to ADP, a method known as phosphorylation.
