ATP is
one of the most important compounds that cells use to store and release energy.
ATP analogy
ATP is a full battery that can be used to perform functions
What is ATP made of?
Adenine, 5-carbon sugar (ribose), and 3 phosphate groups
All 3 of the phosphate groups in ATP are _____ charged
negatively
What is the key to ATP’s ability to store and release energy

Nitrogenous base in DNA (A base)
ADP stands for
Adenosine Diphosphate
ADP is
a compound that looks like ATP, but has TWO phosphate groups instead of 3
ADP can be _____ _____ ___ if a cell has energy
turned into ATP
How would ADP turn into ATP
phosphorylate ADP to turn it into ATP —> this can be done by eating food or photosynthesis
Phosphorylate
to add a phosphate group
How do cells release the energy stored in ATP
By breaking and re-forming the bonds between its phosphate groups
