  2. Cellular Energy Chapter 8 8.3 Cellular Respiration • The net yield from the Krebs cycle is six CO2 molecules, two ATP, eight NADH, and two FADH2.

  3. Cellular Energy Chapter 8 Ch 8 Cellular Energy Using your clicker, check your mastery of Ch 8 objectives from this power point

  4. A B C D Cellular Energy Chapter 8 CDQ 1 Chapter Diagnostic Questions Which statement describes the law of conservation of energy? Energy cannot be converted or destroyed. Energy can be converted and destroyed. Energy can be converted but not destroyed. Energy can be destroyed but not converted.

  5. A B C D Cellular Energy Chapter 8 CDQ 2 Chapter Diagnostic Questions In which metabolic process are molecules broken down to produce carbon dioxide and water? photosynthesis cellular respiration homeostasis fermentation

  6. A B C D Cellular Energy Chapter 8 CDQ 3 Chapter Diagnostic Questions At the end of the Calvin cycle, where is energy stored? NADPH ATP chloroplast glucose

  7. A B Cellular Energy Chapter 8 FQ 1 8.1 Formative Questions Which law of thermodynamics explains why the ladybug receives the least amount of usable energy? the first law of thermodynamics the second law of thermodynamics

  8. A B Cellular Energy Chapter 8 FQ 2 8.1 Formative Questions All of the energy from the food you eat comes from the sun. true false

  9. A B C D Cellular Energy Chapter 8 FQ 4 8.1 Formative Questions Why is adenosine triphosphate (ATP) such an important biological molecule? It captures light energy from the sun. It is produced in anabolic pathways. It stores and releases chemical energy. It converts mechanical energy to thermal energy.

  10. A B C D Cellular Energy Chapter 8 FQ 5 8.2 Formative Questions Where in the plant cell does photosynthesis take place? chloroplasts Golgi apparatus mitochondria vacuoles

  11. A B C Cellular Energy Chapter 8 FQ 6 8.2 Formative Questions Which range of wavelengths is reflected by chlorophylls a and b? 400-500 nm 500-600 nm 600-700 nm

  12. A B C D Cellular Energy Chapter 8 FQ 9 8.3 Formative Questions What is the overall purpose of cellular respiration? to make ATP to process H2O to store glucose to deliver oxygen

  13. A B C D Cellular Energy Chapter 8 FQ 10 8.3 Formative Questions Which represents the general sequence of cellular respiration? TCA cycle  chemiosmosis  glycolysis glycolysis  Krebs cycle  electron transport electron absorption  catalysis  phosphorylation aerobic pathway  anaerobic pathway  fermentation

  14. A B C Cellular Energy Chapter 8 FQ 11 8.3 Formative Questions Which stage of cellular respiration is the anaerobic process? glycolysis Krebs cycle electron transport

  15. A B C D Cellular Energy Chapter 8 FQ 12 8.3 Formative Questions Which molecule generated by the Krebs cycle is a waste product? CoA CO2 FADH2 NADH

  16. A B C D Cellular Energy Chapter 8 CAQ 1 Chapter Assessment Questions Look at the following figure. Which part of the chloroplast is a sac-like membrane arranged in stacks? grana stroma thylakoids Golgi apparatus

  17. A B C D Cellular Energy Chapter 8 CAQ 2 Chapter Assessment Questions During the Krebs cycle, pyruvate is broken down into what compound? H2O O2 CO CO2

  18. A B C D Cellular Energy Chapter 8 CAQ 3 Chapter Assessment Questions Look at the following figure. Which molecule is released when ATP becomes ADP? phosphate group water molecule ribose sugar energy cells

  19. A B Cellular Energy A B Chapter 8 STP 1 Standardized Test Practice Which metabolic process is photosynthesis?

  20. A B C D Cellular Energy Chapter 8 STP 2 Standardized Test Practice At the beginning of photosynthesis, which molecule is split to produce oxygen (O2) as a waste product? CO2 H2O C6H12O6 3-PGA

  21. A B C D Cellular Energy Chapter 8 STP 3 Standardized Test Practice Which molecule helps provide the energy that drives this cycle? 3-PGA CO2 NADPH rubisco

  22. A B C D Cellular Energy Chapter 8 STP 5 Standardized Test Practice What is the final step of cellular respiration? O2 and H+ form H2O. Electrons and H2O generate ATP. C6H12O6 is broken down into CO2. NADH and FADH2 gain electrons.

  23. A B C D Cellular Energy Chapter 8 STP 6 Standardized Test Practice What prevents pyruvate from entering the Krebs cycle and instead results in this pathway? a buildup of CO2 a lack of oxygen an excess of glucose an increased demand for ATP

  24. Chapter 8 Good Luck On tomorrow’s test
