Phosphorylation?

The chemical "battery" that releases energy for many of the biochemical processes in the cell is a molecule called adenosine triphosphate, ATP.  

 

This can hydrolyse to release one or two phosphate groups, plus energy. The reverse process, building up ATP by adding phosphate groups, is what recharges this "battery". This is called phosphorylation and is what the energy from metabolism of carbohydrates, for example, does. The energy released by "burning" carbohydrates such as glucose with oxygen (and producing carbon dioxide and water) generates ATP, for later use in cellular processes that require energy. ATP is universal in life and is thus thought of as probably one of the first bits of common biochemistry to have arisen. Or so I understand.

Hmmmm?  I shall return when my ATP finishes churning and blending all of this.  Thank you. :sherlock:
