Key concepts

3 concepts

  1. 1

    ATP, or adenosine triphosphate, is the energy coinage of all life on our planet.

  2. 2

    ATP consists of adenine, a ribose sugar, and three phosphate groups.

  3. 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.
