The document is the agenda and lesson plan for a biology class. It discusses aerobic and anaerobic respiration. Aerobic respiration requires oxygen and produces more ATP through glycolysis, the Krebs cycle, and the electron transport chain. Anaerobic respiration does not require oxygen and only produces 2 ATP through lactic acid or alcohol fermentation.

1. Biology I Mr. Nettles

2. Agenda – Wed., Nov. 2, 2011 Warm-Up: EOC Questions Lesson: Anaerobic vs. Aerobic Wrap-Up: Review Questions from Lesson Homework: Summarization Worksheet (due at beginning of class tomorrow!) Tomorrow: Review Day!! Friday: Major Quiz!!

3. Today’s Objectives I will define aerobic and anaerobic respiration. I will compare and contrast aerobic and anaerobic respiration.

4. binds to specific active sites stores genetic information transports amino acids to ribosomes produces chromosomes for sexual reproduction What is the primary function of DNA In organisms? Warm-Up (Nov. 2)

5. lipids proteins nucleic acids carbohydrates Which molecules store and transmit genetic information ? Warm-Up (Nov. 2)

6. swell when exposed to salt. absorb the extra salt. release water in the presence of salt. lose oxygen when in contact with salt. 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. Aerobic and Anaerobic Respiration Cellular respiration is a type of aerobic respiration because it requires oxygen .

8. Aerobic and Anaerobic Respiration Cellular respiration occurs in three main parts . Glycolysis Krebs Cycle (citric acid cycle) Electron Transport Chain

9. Glycolysis Glucose is broken down into pyruvic acid. Two molecules of ATP and two molecules of NADH are formed for each molecule of glucose that is broken down. Aerobic and Anaerobic Respiration

10. Krebs Cycle (citric acid cycle) The Krebs Cycle produces six CO 2 (carbon dioxide) molecules, two ATP, eight NADH, and two FADH 2 . Aerobic and Anaerobic Respiration The series of reactions in which pyruvic acid is broken down into carbon dioxide . NADH and FADH 2 carry high-energy electrons .

11. Krebs Cycle (citric acid cycle) Aerobic and Anaerobic Respiration

12. Electron Transport Chain Aerobic and Anaerobic Respiration NADH and FADH 2 release high-energy electrons (H + ) to produce ATP. NADH becomes NAD + FADH 2 becomes FAD Uses ten NADH molecules from glycolysis and the Krebs Cycle to make 30 ATP . Uses two FADH 2 molecules from the Krebs Cycle to make 4 ATP .

13. Aerobic and Anaerobic Respiration Summary of Cellular Respiration (Aerobic Respiration) 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. Aerobic and Anaerobic Respiration Anaerobic Respiration does not require oxygen. Only two ATP are produced Two Types: Lactic Acid Fermentation – used to make foods such as cheese and yogurt Alcohol Fermentation – used to make beer and wine

15. What are are the three main stages of cellular respiration ? Wrap-Up (Nov. 2) How are aerobic respiration and anaerobic respiration different? Count the total number of ATP produced from cellular respiration. (Hint: Glycolysis + Krebs Cycle + Electron Transport Chain )
