Energy and Life

Adenosine Triphosphate (ATP)
Adenosine triphosphate (ATP) is one of the most important
compounds that cells use to store and release energy.

ribose 3 phosphate groups

adenine

Adenosine Diphosphate (ADP)
Adenosine diphosphate (ADP) has two phosphate groups
instead of three.

adenine

ribose

2 phosphate groups

Storing Energy
When a cell has energy available, it can store small
amounts of it by adding phosphate groups to ADP
molecules, producing ATP.

Releasing Energy
When a cell needs energy, it can release it by breaking
the bond between the second and third phosphate
groups in ATP.

ATP and Batteries

ATP Production
Cells must produce ATP. In photosynthesis, plants convert
the energy of sunlight into chemical energy stored in the
bonds of carbohydrates.
