| | Cellular Currency: ATP |
 | | What makes ATP different from other nucleotides such as cytosine, thymine, guanine, and adenine, is that it is used widely as a carrier of chemical energy. |
 | | ATP is used to drive active transport, and other chemical reactions such as photosynthesis, and cellular respiration. |
 | | ATP is broken down by hydrolysis (reaction with water), which yields adenosine diphosphate (ADP), inorganic phosphorous, and energy. |
