Learning Objective
ATP powers cellular work by coupling exergonic reactions to endergonic reactions.
- 1
ATP, or adenosine triphosphate, is the energy coinage of all life on our planet.
- 2
ATP consists of adenine, a ribose sugar, and three phosphate groups.
- 3
When ATP is hydrolyzed, it becomes ADP + Pᵢ, releasing energy that can be used for cellular work such as active transport and muscle contraction.
