  2. http://www.newtonswindow.com/problem-solving.htm Remember from BIO 1 _____________ can make their own food usingenergy from sunlight. AUTOTROPHS Ex: Green plants, a few bacteria http://www.seorf.ohiou.edu/~tstork/compass.rose/photosynthesis/chloro_sun_bathing.gif

  3. http://www.newtonswindow.com/problem-solving.htm Remember from BIO 1 HETEROTROPHS __________________ get energy by consumingother organisms Ex: Animals, fungi, most bacteria http://www.epa.gov/region5/superfund/ecology/images/fishcartoon.gif

  4. Remember from BIO 1 WHAT DO CELLS USE ENERGY FOR ? ACTIVE TRANSPORT Na+ - K + PUMPEndocytosis Exocytosis Images: http://www.newtonswindow.com/problem-solving.htm http://www.lionden.com/cell_animations.htm http://academic.brooklyn.cuny.edu/biology/bio4fv/page/cell-movement.html Animation from:

  5. WHAT DO CELLS USE ENERGY FOR ? Movement Synthesis of biomolecules Reproduction Meiosis: http://www.tokyo-med.ac.jp/genet/anm/ Cilia: http://www.sk.lung.ca/content.cfm?edit_realword=hwbreathe Replication: http://www.beyondbooks.com/lif71/4c.asp Transcription:http://www.wappingersschools.org/RCK/staff/teacherhp/johnson/visualvocab/mRNA.gif Translation:

  6. 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 ATP Image by: Riedell

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

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

  9. http://www.cat.cc.md.us/~gkaiser/biotutorials/energy/adpan.htmlhttp://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→ ____ + ____ + ADP

  10. Cells ________ energy by adding the phosphate back on to ADP to make ATP. STORE The energy to do this comes from ____________ like _____________ FOODS GLUCOSE It’s like recharging the battery ! ADP+ ___ + ________ → ___ ATP

  11. ATP is useful BUT . . . NOT LARGE 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___________. LONG TERM 90 times glucose http://www.estrellamountain.edu/faculty/farabee/biobk/BioBookCHEM2.html

  12. http://www.newtonswindow.com/problem-solving.htm Remember from BIO 1 Example: GLUCOSE C6H12O6 CARBOHYDRATES containCarbon, Hydrogen, & Oxygen (with a ratio of 1 C: 2 H: 1 O) Image from: http://www.estrellamountain.edu/faculty/farabee/biobk/BioBookCHEM2.html

  13. MONOSACCHARIDESSingle sugar molecules C6H12O6 C6H12O6 C6H12O6 http://www.estrellamountain.edu/faculty/farabee/biobk/BioBookCHEM2.html http://217.60.75.10/llt/biokemi/images/galactose.jpg http://217.60.75.10/llt/biokemi/images/galactose.jpg http://www.estrellamountain.edu/faculty/farabee/biobk/BioBookCHEM2.html C5H10O5

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

  15. 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

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

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