adenosine triphosphate

Adenosine triphosphate (ATP) is a molecule that acts as the primary energy carrier in all living cells. It stores energy in its phosphate bonds, which can be released to power various biological processes like muscle movement, nerve signals, and chemical reactions. When cells need energy, ATP is broken down into ADP (adenosine diphosphate) and a phosphate group, releasing energy. Cells continuously regenerate ATP from ADP and phosphate using nutrients obtained from food, ensuring they have a ready supply to perform vital functions. In essence, ATP is the energy currency that keeps living organisms functioning.
