Remember!
ONE SPECIAL KIND of NUCLEOTIDE is used by cells to store and transport ENERGY
CELLS USE ATP TO STORE and RELEASE ENERGY
ATP = __________________________Adenosine triphosphate
____ PHOSPHATE GROUPS
3
ATP can change into ADP
ADP = __________________________Adenosine diphosphate
____ PHOSPHATE GROUPS
2
ATP → ____ + ____ +
http://www.cat.cc.md.us/~gkaiser/biotutorials/energy/adpan.html
ATP releases energy stored in a high energychemical bond by removing the phosphate and becoming ADP
ADP
ADP + ___ + ________ → ___
The energy to do this comes from
____________ like _____________
Cells ________ energy by adding the phosphate back on to ADP to make ATP.
ATP
It’s like recharging the battery !
STORE
FOODS GLUCOSE
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___________.http://www.estrellamountain.edu/faculty/farabee/biobk/BioBookCHEM2.html

Remember!CARBOHYDRATES containCarbon, Hydrogen, & Oxygen (with a ratio of 1 C: 2 H: 1 O)
C-C and C-H bonds are HIGH ENERGY bonds!
MONOSACCHARIDES
