  1. TOPIC: Cell Processes AIM: Explain the two types of respiration. Do Now: HW: Bring in Science Board Wednesday or Monday!

  2. Cell Respiration • Glucose (sugar) is broken down to make ENERGY (ATP) • Occurs in mitochondria • Carried out by every living thing!!!

  3. Aerobic Respiration • Oxygen (O2) required to make energy

  4. Oxygen Carbon dioxide & water vapor

  5. EQUATION C6H12O6 + 6O2 6CO2 + 6H2O + 36ATP GLUCOSE + OXYGEN CARBON + WATER + ENERGY DIOXIDE Raw materials Products

  6. Anaerobic Respiration • Energy produced WITHOUT oxygen • FERMENTATION • Occurs in the cytoplasm

  7. EQUATION C6H12O6 6CO2 + 2ATP GLUCOSECARBON + ENERGY DIOXIDE Raw materials Products

  8. Aerobic respiration Anaerobic respiration

  9. 2 types of anaerobic respiration 1. ALCOHOLIC FERMENTATION = • In yeast cells

  10. C6H12O6alcohol + CO2+2ATP

  11. 2. LACTIC ACID FERMENTATION = • In your muscles, when oxygen is not available

  12. C6H12O6 lactic acid + 2ATP

  13. Let’s summarize… • Explain why the process of respiration is so important. • Explain the difference between the two types of respiration. • What nutrient is used in both types of respiration? • Which type of respiration is more efficient?

  14. Review: Yeast cells undergoing anaerobic respiration produce carbon dioxide and (1.) water (2.) ethyl alcohol (3.) nitrogen (4.) glucose

  15. 2. During the process of respiration, energy from the oxidation of glucose is stored in molecules of (1.) DNA (2.) ADP (3.) ATP (4.) RNA

  16. 3. In the presence of oxygen, _____ molecules of ATP can be formed. (1.)2       (2.) 19         (3.) 36           (4.) 63

  17. 4. Which process yields lactic acid and small amounts of usable energy? (1.) photosynthesis (2.) aerobic respiration (3.) anaerobic respiration (4.) chemosynthesis

  18. 5. The net yield of ATP from the process of fermentation is (1.) 2 (2.) 4 (3.) 34 (4.) 36

  19. 6. Muscles cells engaged in vigorous activity build up relatively high concentrations of (1.) lactic acid (2.) pyruvic acid (3.) alcohol (4.) oxygen

  20. 7. Where do the final stages of cellular respiration appear to take place? (1.) along the endoplasmic reticulum (2.) in the cytoplasm (3.) on the surface of ribosomes (4.) within the mitochondria

  21. 8. Aerobic respiration and fermentation are similar in that BOTH processes (1.) require oxygen (2.) use light energy (3.) release energy (4.) produce glucose

  22. 9. During aerobic respiration, the chemical energy of a glucose molecule is gradually released, producing 36 ATP and (1.) NH3 and O2 (2.) NH3 and CO2 (3.) H2O and O2 (4.) H20 and CO2

  23. Review: Which statement is not a part of the cell theory? (1)Cells are the basic unit of structure of living things. (2) Cells are the basic unit of function of living things. (3) Cell parts such as chloroplasts are self-replicating. (4) Cells come from preexisting cells.

  24. Which structure permits the entry and exit of materials in an animal cell? 1. lysosome 2. chromosome 3. cell wall 4. cell membrane

  25. The structure most closely associated with the destruction of worn out cell organelles is the • lysosome 2. centrosome • 3. vacuole 4. chromosome

  26. Whitney observes a cell under the microscope. She identifies it as a green plant cell and not a cheek cell because of a (1.) nucleus (2.) cell membrane (3.) cell wall (4.) mitochondrion

  27. Which structure is found ONLY in animal cells? (1.) cell wall (2.) vacuoles (3.) centrioles (4.) chloroplasts

  28. The organelle most closely associated with the manufacture of proteins within the cell is the (1.) ribosome (2.) nucleolus (3.) cell wall (4.) cell membrane
