6. ATP Image by: Riedell http://www.newtonswindow.com/problem-solving.htm Remember from BIO 1 ONE SPECIAL KIND of NUCLEOTIDE is used by cells to store and transport ENERGY

7. CELLS USE ATP TO STORE and RELEASE ENERGY ATP = __________________________ Adenosine triphosphate ____ PHOSPHATE GROUPS 3

8. ATP can change into ADP ADP = __________________________ Adenosine diphosphate ____ PHOSPHATE GROUPS 2

9. ATP → ____ + ____ + 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 ADP

10. 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 FOODSGLUCOSE

11. Watch a video clip about ATP FORMATION (8A)

12. 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 NOTLARGE LONG TERM 90 times glucose

13. Example: GLUCOSE C 6 H 12 O 6 Image from: http://www.estrellamountain.edu/faculty/farabee/biobk/BioBookCHEM2.html http://www.newtonswindow.com/problem-solving.htm Remember from BIO 1 CARBOHYDRATES contain Carbon, Hydrogen, & Oxygen (with a ratio of 1 C: 2 H: 1 O)

14. MONOSACCHARIDES Single sugar molecules C 6 H 12 O 6 http://www.estrellamountain.edu/faculty/farabee/biobk/BioBookCHEM2.html http://217.60.75.10/llt/biokemi/images/galactose.jpg http://www.estrellamountain.edu/faculty/farabee/biobk/BioBookCHEM2.html C 5 H 10 O 5

15. CARBOHYDRATES SUPPLY ENERGY Images from: http://www.miranda.com/library.en/Images/Pictures/girls-runners.jpg http://www.estrellamountain.edu/faculty/farabee/biobk/BioBookCHEM2.html Cells burn GLUCOSE for their energy needs Remember from BIO 1

16. CARBOHYDRATES are building blocks for other molecules ATP DNA & RNA POLYSACCHARIDES http://www.estrellamountain.edu/faculty/farabee/biobk/BioBookCHEM2.html ATP by Riedell http://evolution.berkeley.edu/evosite/evo101/images/dna_bases.gif http://sps.k12.ar.us/massengale/biochemistry_notes_bi_ch3.htm

17. Starch Glucose Section 2-3 Remember from BIO 1

18. Molecules made by joining MANY sugar molecules together are called ___________________ POLYSACCHARIDES EXAMPLES: Image from: http://bioweb.wku.edu/courses/BIOL115/Wyatt/Biochem/Carbos/Carb_poly.gif

19. GLYCOGEN is the way _________ cells store GLUCOSE to use later. Image from: http://www.msu.edu/course/lbs/145/smith/s02/graphics/campbell_5.6.gif ANIMAL CARBOHYDRATES SUPPLY ENERGY

20. STARCH is the way _______ cells store GLUCOSE for later. Images from: http://bioweb.wku.edu/courses/BIOL115/Wyatt/Biochem/Carbos/Carb_poly.gif http://oregonstate.edu/instruction/bb450/stryer/ch21/Slide24.jpg PLANT CARBOHYDRATES SUPPLY ENERGY
