Chapter 3.7, Problem 3MQ
Summary Introduction
Adenosine triphosphate (ATP) molecule is used as an energy currency of the cell. It is composed of three molecules of phosphate attached to the adenosine ribonucleoside. The energy is released by hydrolyzing the bond between three phosphate molecules to adenosine.
