  1. CELLULAR RESPIRATION Chemical Pathways Chapter 9-1 http://www.clickatutor.com/mitochondria.jpg

  2. http://www.inclusive.co.uk/downloads/images/pics2/tree.gif AUTOTROPHS ___________ use energy from sunlight or chemicals to make their own food In the last chapter green plants used ________________ to trap energy from __________ and make ______________ PHOTOSYNTHESIS sunlight food (glucose) http://206.173.89.42/REALTYWITHALOHA_COM/piphoto/funny%20sun%20with%20sunglasses.gif

  3. In this chapter, we will learn how this glucose is ____________ by organisms and the _______ is stored as _______ in a process called ___________________ broken down energy ATP CELLULAR RESPIRATION What kind of organisms do this?

  4. What kind of organisms do this? plants fungi animals bacteria ________ (Including _______) ______ ______ ______ humans ALL LIVING THINGS NEED ENERGY!

  5. How do we get the sugar from the plants? REMEMBER! _______________ get their energy by eating other organisms. HETEROTROPHS We get the energy the plants stored as glucose by _____________ directly or eating the _________ that ate the plants. eating plants animals  Image from: http://ag.ansc.purdue.edu/sheep/ansc442/Semprojs/2003/spiderlamb/eatsheep.gif http://www.cibike.org/Eating.htm

  6. REMEMBER CELL BIO

  7. Image from: http://vilenski.org/science/safari/cellstructure/cytoplasm.html Area with gel-like material inside cell membrane surrounding mitochondria = ______________________ Power plant of cell that burns glucose and stores the energy as ATP = _______________ CYTOPLASM mitochondria http://www.clickatutor.com/mitochondria.jpg

  8. DOUBLE MITOCHONDRIA = cell power plant Surrounded by ___________ membrane Outer membrane & Inner membrane (called _______________ ) Space between inner membrane & outer membrane = ____________________ Space inside cristae folds = _________________ CYTOPLASM surrounds mitochondria CRISTAE INTERMEMBRANE SPACE MATRIX

  9.  Image from: http://www.cat.cc.md.us/~gkaiser/biotutorials/energy/adpan.html All organisms (heterotrophs AND autotrophs) use the _____________ to charge up their _______ energy in food ATP

  10. ATP This process of releasing the energy from FOOD (glucose) to make _____ = ________________ CELLULAR RESPIRATION  Image by Riedell Image from: http://www.biologyclass.net/mitochondria.jpe

  11. slowly many steps CELLULAR RESPIRATION happens __________ in ________________. If all the energy was released in one step… most would be lost as ____________________! light and heat http://plato.acadiau.ca/COURSES/comm/g5/Fire_Animation.gif

  12. PHOTOSYNTHESIS ___________ + _________ + ___________ →_______________ + __________ 6 CO2 6 H2O C6H12O6 6O2 CELLULAR RESPIRATION C6H12O6 6 CO2 _____________ + _________ →________ + __________ + __________ ______________________________________________________________ 6O2 6 H2O The two equations are exact opposites!

  13. Calorie vs. calorie • http://www.copernicusproject.ucr.edu/ssi/HighSchoolBioResources/Cellular%20Respiration/Cellular%20Respiration%20PPT/Calories__Measuring_Heat.asf

  14. http://hesperia.gsfc.nasa.gov/sftheory/images/boilingif UNITS FOR MEASURING HEAT ENERGY Amount of heat it takes to raise 1 gram of water 1◦ Celsius = _______________ Unit for measuring energy in food = _______________ 1 Calorie = _________ calories calorie Calorie 1000 http://www.raytechcatalog.com/images/products/mainstay_food_3600_nutrition.gif

  15. NADP+ Remember from Photosynthesis? High energy electron carrier = ___________ Cellular respiration uses some different carriers to transport high energy electrons. _______ & ________ NAD+ FAD ________ + _________ → ____________ 2 e- + H+ NAD+ ________ + _________ →____________ FAD 2 e- + 2H+

  16. The first step in cellular respiration = __________________ Glycolysis happens in the ________________ outside the mitochondria GLYCOLYSIS http://www.brookings.k12.sd.us/biology/ch9respiration/Chapter%2009B.mpg CYTOPLASM

  17. Glycolysis (GLYKOS = ________ LYSIS= ___________ ) Glycolysis ____________________________ BUT it needs some ____________to get it started. What molecule do you think is going to supply the energy do this? sweet split apart DOES NOT REQUIRE OXYGEN ENERGY ATP

  18. GLYCOLYSIS ________ ↓ ___________ → →_____________ ↓ ____________________ + _______________ GLUCOSE 2 PYRUVIC ACID ATP ATP ATP ATP NADH NADH 4 ATP’s 2 ATP’s PUT IN ________ and GET BACK __________ Net gain of ________ and __________ 2 ATP’s 2 NADH

  19. = ANAEROBIC PYRUVIC ACID MOVES TO NEXT STEP IF THERE IS NO OXYGEN (______________) IF THERE IS OXYGEN (_____________) = AEROBIC

  20. WITHOUT PYRUVIC ACID ___________ OXYGEN 2 kinds of fermentation ___________________ & _____________________ ANAEROBIC Alcoholic Lactic acid

  21. ALCOHOLIC FERMENTATION _______ +_____ →__________ + ______ + _____ PYRUVIC ACID ALCOHOL CO2 NAD+ Happens when yeast makes bread dough rise CO2 bubbles make _____________ in bread Alcohol _______________ during cooking air spaces evaporates http://www.deliciousdelicious.com/archives/herb%20bread%201.jpg

  22. ALCOHOLIC FERMENTATION _______ +_____ →__________ + ______ + _____ PYRUVIC ACID ALCOHOL CO2 NAD+ Happens when ___________ make _______ or ____________ make ______ beer yeast bacteria wine http://www.firstpath.com/images/alcohol.jpg

  23. LACTIC ACID FERMENTATION _______ +_____ →______________ + ________ PYRUVIC ACID LACTIC ACID NAD+ muscles Happens in _____________ during ____________when body can’t get oxygen to tissues fast enough. Lactic acid builds up in muscles causing soreness exercise http://www.miranda.com/library.en/Images/Pictures/girls-runners.jpg

  24. LACTIC ACID FERMENTATION _______ +_____ →______________ + ________ PYRUVIC ACID LACTIC ACID NAD+ Happens when bacteria are used to make __________and ____________ like: Yogurt, buttermilk, sauerkraut, pickles, cheese sour cream, & kimchi food beverages http://chronicle.augusta.com/images/headlines/032200/DANNON_YOGURT.jpg http://www.reillydairy.com/natural_cheese.html

  25. WHY DO FERMENTATION? WHY NOT JUST KEEP MAKING ATP USING GLYCOLYSIS? WITHOUT OXYGEN, PYRUVIC ACID ___________ and all the _______ carriers get full. Eventually glycolysis will builds up NAD+ NAD+

  26. _______ +_____ →__________ + ______ + _____ PYRUVIC ACID CO2 NAD+ ALCOHOL → NAD+ LACTIC ACID ______ → You get the NAD+ carriers back FERMENTATION HAPPENS so cells can ____________________ needed to keep glycolysis going REGENERATE the NAD+

  27. Flooded Corn Field Plants do ____________ but plants need ______________________ too. If plants seeds are under water 3 days or more, the seeds will die. If a plants roots are under water for 3 days or more, the plants will die. photosynthesis By:http://skyways.lib.ks.us/towns/ElkCity/2007flood.html oxygen for cellular respiration
