Nov. 2 (aerobic vs. anaerobic)

  1. 1. Biology I Mr. Nettles
  2. 2. Agenda – Wed., Nov. 2, 2011 <ul><li>Warm-Up: EOC Questions </li></ul><ul><li>Lesson: Anaerobic vs. Aerobic </li></ul><ul><li>Wrap-Up: Review Questions from Lesson </li></ul><ul><li>Homework: Summarization Worksheet (due at beginning of class tomorrow!) </li></ul><ul><li>Tomorrow: Review Day!! </li></ul><ul><li>Friday: Major Quiz!! </li></ul>
  3. 3. Today’s Objectives <ul><li>I will define aerobic and anaerobic respiration. </li></ul><ul><li>I will compare and contrast aerobic and anaerobic respiration. </li></ul>
  4. 4. <ul><li>binds to specific active sites </li></ul><ul><li>stores genetic information </li></ul><ul><li>transports amino acids to ribosomes </li></ul><ul><li>produces chromosomes for sexual reproduction </li></ul>What is the primary function of DNA In organisms? Warm-Up (Nov. 2)
  5. 5. <ul><li>lipids </li></ul><ul><li>proteins </li></ul><ul><li>nucleic acids </li></ul><ul><li>carbohydrates </li></ul>Which molecules store and transmit genetic information ? Warm-Up (Nov. 2)
  6. 6. <ul><li>swell when exposed to salt. </li></ul><ul><li>absorb the extra salt. </li></ul><ul><li>release water in the presence of salt. </li></ul><ul><li>lose oxygen when in contact with salt. </li></ul>A student notices that the lettuce in a salad wilts soon after salt is added. Wilting most likely occurs because the lettuce cells: Warm-Up (Nov. 2)
  7. 7. Aerobic and Anaerobic Respiration <ul><li>Cellular respiration is a type of aerobic respiration because it requires oxygen . </li></ul>
  8. 8. Aerobic and Anaerobic Respiration <ul><li>Cellular respiration occurs in three main parts . </li></ul><ul><li>Glycolysis </li></ul><ul><li>Krebs Cycle (citric acid cycle) </li></ul><ul><li>Electron Transport Chain </li></ul>
  9. 9. Glycolysis <ul><li>Glucose is broken down into pyruvic acid. </li></ul><ul><li>Two molecules of ATP and two molecules of NADH are formed for each molecule of glucose that is broken down. </li></ul>Aerobic and Anaerobic Respiration
  10. 10. Krebs Cycle (citric acid cycle) <ul><li>The Krebs Cycle produces six CO 2 (carbon dioxide) molecules, two ATP, eight NADH, and two FADH 2 . </li></ul>Aerobic and Anaerobic Respiration <ul><li>The series of reactions in which pyruvic acid is broken down into carbon dioxide . </li></ul><ul><li>NADH and FADH 2 carry high-energy electrons . </li></ul>
  11. 11. Krebs Cycle (citric acid cycle) Aerobic and Anaerobic Respiration
  12. 12. Electron Transport Chain Aerobic and Anaerobic Respiration <ul><li>NADH and FADH 2 release high-energy electrons (H + ) to produce ATP. </li></ul><ul><ul><li>NADH becomes NAD + </li></ul></ul><ul><ul><li>FADH 2 becomes FAD </li></ul></ul><ul><li>Uses ten NADH molecules from glycolysis and the Krebs Cycle to make 30 ATP . </li></ul><ul><li>Uses two FADH 2 molecules from the Krebs Cycle to make 4 ATP . </li></ul>
  13. 13. Aerobic and Anaerobic Respiration <ul><li>Summary of Cellular Respiration (Aerobic Respiration) </li></ul>Process What Happens? What’s Made? Glycolysis glucose breaks down into pyruvic acid 2 ATP 2 NADH Krebs Cycle pyruvic acid is broken down into carbon dioxide 2 ATP 8 NADH 2 FADH 2 Electron Transport Chain ATP is formed from the transport of high-energy electrons 34 ATP
  14. 14. Aerobic and Anaerobic Respiration <ul><li>Anaerobic Respiration does not require oxygen. </li></ul><ul><ul><li>Only two ATP are produced </li></ul></ul><ul><ul><li>Two Types: </li></ul></ul><ul><ul><ul><li>Lactic Acid Fermentation – used to make foods such as cheese and yogurt </li></ul></ul></ul><ul><ul><ul><li>Alcohol Fermentation – used to make beer and wine </li></ul></ul></ul>
  15. 15. <ul><li>What are are the three main stages of </li></ul><ul><li>cellular respiration ? </li></ul>Wrap-Up (Nov. 2) <ul><li>How are aerobic respiration and anaerobic </li></ul><ul><li>respiration different? </li></ul><ul><li>Count the total number of ATP produced </li></ul><ul><li>from cellular respiration. </li></ul><ul><li>(Hint: Glycolysis + Krebs Cycle + Electron Transport Chain ) </li></ul>
