Presentation Transcript

  1. CELLULAR RESPIRATION

  2. CELLULAR RESPIRATION • WHAT IS ENERGY??

  3. CELLULAR RESPIRATION • WHAT IS ENERGY? • ENERGY IS THE ABILITY TO DO WORK • WHAT IS WORK? • WORK IS ANYTHING THAT USES ENERGY • UUUMMM….ANYONE NOTICE A PROBLEM WITH THAT CIRCULAR LOGIC

  4. CELLULAR RESPIRATION • WORK IS MAKING SOMETHING HAPPEN THAT WOULDN’T HAPPEN NATURALLY…ENERGY GIVES YOU THE ABILITY TO DO THIS • WHAT ARE SOME EXAMPLES OF THINGS WE MUST “MAKE HAPPEN” TO SURVIVE?? • THE LIFE PROCESSES!!! • H.N.T.R.S.G.E.R.M.R

  5. CELLULAR RESPIRATION • WHERE DOES THE ENERGY TO DO THIS WORK COME FROM???

  6. CELLULAR RESPIRATION • THIS BEGS THE QUESTION…HOW DOES EATING FOOD EQUAL HAVING ENERGY TO DO CELLULAR WORK? • THE ANSWER: CELLULAR RESPIRATION

  7. CELLULAR RESPIRATION • IN ORDER TO UNDERSTAND CELLULAR RESPIRATION, WE MUST FIRST UNDERSTAND ATP • ATP IS THE “FUEL OF THE CELL” • JUST LIKE OIL MUST BE CONVERTED TOGAS, SUGAR MUST BE CONVERTED TO ATP

  8. CELLULAR RESPIRATION • WHAT IS ATP? • ADENOSINE TRI-PHOSPHATE • HIGH ENERGY COMPOUND • DOES ITS SHAPE LOOK FAMILIAR?

  9. CELLULAR RESPIRATION

  10. CELLULAR RESPIRATION • THE GOAL OF CELLULAR RESPIRATION IS TO USE THE ENERGY IN FOOD TO CONVERT ADP INTO ATP… • IN EFFECT, “STORING” OR “CONVERTING” THE ENERGY FROM THE FOOD INTO ATP • THIS MAKES THE ENERGY IN FOOD, USABLE BY THE CELL

  11. CELLULAR RESPIRATION • THERE ARE TWO MAJOR TYPES OF CELLULAR RESPIRATION • AEROBIC VS ANAEROBIC RESPIRATION

  12. CELLULAR RESPIRATION • THE FIRST PARTS OF AEROBIC AND ANAEROBIC RESPIRATION ARE IDENTICAL • GLYCOLYSIS • “GLYCO” + “LYSIS” • THE BREAKDOWN OF GLUCOSE • GLUCOSE  PYRUVIC ACID

  13. CELLULAR RESPIRATION • WHAT HAPPENS AFTER GLYCOLYSIS DEPENDS ON THE PRESENCE OF OXYGEN • NO OXYGEN = ANAEROBIC RESPIRATION • OXYGEN = AEROBIC RESPIRATION • ANAEROBIC RESPIRATION NEXT STEP IS CALLEDFERMENTATION!!

  14. CELLULAR RESPIRATION • FERMENTATION • ANAEROBIC PROCESS • TWO VERSIONSLACTIC ACID VS.ALCOHOLIC • ALCOHOLIC IS WHATKEEPS THE BEERCOMPANIES IN BUSINESS!!

  15. CELLULAR RESPIRATION

  16. CELLULAR RESPIRATION • DO HUMANS PERFORM ALCOHOLIC FERMENTATION? • HOW DO YOU KNOW? • IF NOT ALCOHOLIC FERMENTATION, THEN WHAT? • LACTIC ACID FERMENTATION • HOW DO YOU KNOW??

  17. CELLULAR RESPIRATION • AEROBIC RESPIRATION • REQUIRES OXYGEN • OCCURS IN THE MITOCHONDRIA!!!

  18. CELLULAR RESPIRATION • TWO MAJOR STEPS OF AEROBIC RESPIRATION • KREBS CYCLE

  19. CELLULAR RESPIRATION • TWO MAJOR STEPS OF AEROBIC RESPIRATION • ELECTRON TRANSPORT CHAIN

  20. CELLULAR RESPIRATION • KEY TERMS OF ELECTRON TRANSPORT CHAIN • CRISTAE • CHEMIOSMOSIS • PROTON GRADIENT • ATP SYNTHASE

  21. CELLULAR RESPIRATION • OVERALL EQUATION

  22. CELLULAR RESPIRATION • OVERALL REACTION

  23. CELLULAR RESPIRATION • IF CELLULAR RESPIRATION IS ALWAYS TAKING PLACE, WHY DO HUMANS GET TIRED WHEN EXERCISING??

  24. CELLULAR RESPIRATION • WHY DO WE ONLY LOOK AT SUGAR IN THIS EQUATION?

  25. CELLULAR RESPIRATION • WHY IS IT NECESSARY TO CONVERT GLUCOSE INTO ATP? • CELLULAR RESPIRATION DOES THIS CONVERSION…BUT WHERE DOES THE GLUCOSE COME FROM TO BEGIN WITH? • THAT’S UP NEXT!!!
