ATP= ENERGY BIOLOGY I

ATP ATP = Adenosine Triphosphate Is used to store and release energy Is made when organisms break down food Has three parts Adenine Ribose sugar Three phosphate group Think of ATP as a fully charged battery

ATP STRUCTURE

ADP ADP= Adenosine Diphosphate Has three parts Adenine Ribose sugar Two phosphate group Think of ADP as a half charged battery

ADP STRUCTRE

ADP + 1 phosphate = ATP When the extra phosphate is added to ADP energy is stored ( the half charged battery is now fully charged)

ATP- 1 Phosphate = ADP + ENERGY When a phosphate group is removed from ATP energy is released. (the fully charged battery is now half charged)

ENERGY ATP is used to store energy but not for long periods of time (lipids are used to energy for long periods of time) Cells use the energy from carbohydrates to add phosphate to ADP to keep creating ATP when needed.
