Explain how adenosine can gain and lose a phosphate molecule.

ATP works by losing the endmost phosphate which is gathered when taught to do as such by a compound. This response liberates a ton of vitality, which would then be able to be used to manufacture proteins, contract muscles, and so forth. The result is adenosine diphosphate (ADP), and the phosphate atom. Even more vitality can be removed by expelling a moment phosphate gathering to create adenosine - monophosphate (AMP). When the body is inactive and vitality isn't promptly essential, the reversal response happens and the phosphate gather is reattached to the atom utilizing vitality got from sustenance
