CELLS USE ATP TO STORE and
RELEASE ENERGY
____ PHOSPHATE
GROUPS
ATP = __________________________
ATP can change into ADP
____ PHOSPHATE
GROUPS
ADP = __________________________
http://www.cat.cc.md.us/~gkaiser/biotutorials/energy/adpan.html
ATP releases
energy stored
in a high energy
chemical bond by
removing the
phosphate and
becoming ADP
ATP
→ ____ + ____ +
Cells ________ energy by adding the
phosphate back on to ADP to make ATP.
The energy to do this comes from
____________ like _____________
It’s like recharging the battery !
ADP + ___ + ________
→ ___
Watch a video clip about
ATP FORMATION (8A)
ATP is useful BUT . . .
ATP is great for TRANSFERRING ENERGY,
but _____ good for storing ________
amounts of energy for the ______________.
A single molecule of GLUCOSE stores more
than _________the chemical energy.
Cells only keep enough ATP
around to last a few seconds and
recharge it by burning___________.
