Presentation Transcript

  1. CELLULAR ENERGIES

  2. Where is energy created in a eukaryotic cell?

  3. What about in prokaryotic cells?

  4. What is energy in biology? ATP Adenosine TriPhosphate Whoa!HOT stuff!

  5. ATP: energy molecule

  6. What is energy? Calorie = Energy A calorie is a heat unit of energy

  7. ATP CYCLE

  8. How do we define Cellular Respiration? Release energy from food to make ATP

  9. Who does Respiration? All Living Organisms!

  10. Aerobic Resp Anaerobic Resp. Req. OXYGEN NO OXYGEN Makes a LITTLE ATP Makes a LOT ATP

  11. Aerobic or Anaerobic? BACTERIA PROTIST FUNGUS (YEAST) PLANTS ANIMALS

  12. ANAEROBIC 1st Step: Glycolysis – Splitting of Glucose EXERGONIC (energy releasing) Phosphorylation NAD

  13. Where does glycolysis occur? CYTOPLASM

  14. Flow Chart

  15. FERMENTATION Respiration with NO oxygen

  16. Chapter 23 Bacteria and Yeast in Food Production

  17. What happens to the pyruvate? FERMENTATION: yeast & bacteria

  18. Fermentation in Humans Lack of Oxygen Build up of Lactic Acid in Muscles

  19. IN HUMANS

  20. Choose your own adventure!

  21. AEROBIC RESPIRATION Where does it occur in a cell?

  22. Why the extra layers? Increase Surface Area MITOCHONDRIA

  23. AEROBIC RESPIRATION If O2 is present! Pyruvate STEP 1: Glycolysis Pyruvate Glucose STEP 2: Kreb Cycle STEP 3: Electron Transport Chain (ETC)

  24. From Food To ATP

  25. ATP released for cellular work CO2 + H2O Glucose many tiny steps

  26. All organic molecules!

  27. Who does photosynthesis?

  28. Chemoautotrophs

  29. CHLOROPLAST Increase Surface Area

  30. CHLOROPHYLL • green pigment • converts solar energy into chemical energy (ATP)

  31. The World of Plants: Photosynthesis US

  32. Light RxN Dark RxN
