ADENOSINE TRIPHOSPHATE (ATP)
Energy currency
Energy from respiration used to make ATP from adenosine diphosphate (ADP) and
inorganic phosphate (Pi)
ATP is hydrolyzed to release energy where it is needed in cells


STRUCTURE OF ATP
Organic base adenine
Pentose sugar ribose
3 phosphate groups

USES OF ATP
ATP cannot be stored so is synthesized as it is required
