1. Cellular Respiration November 16

2. Do Now Collect returned assignments (in hanging folders) Pick up a new tracker Begin working on today’s warm-up: What is aerobic exercise?

3. Upcoming assessments Individual! Quizlet on Tuesday/Wednesday – Food webs & Energy flow – Photosynthesis Individual! Quest on Monday/Tuesday – Food webs & Energy Flow – Photosynthesis – Cellular Respiration – Carbon Cycle – 1 question recycled from Quiz 1

4. Photosynthesis & Energy Flow Concept Check

5. Where do plants get their energy?

6. Photosynthesis & Energy Flow Concept Check Where do plants get their energy?

7. Photosynthesis & Energy Flow Concept Check What is the equation for photosynthesis?

8. Photosynthesis & Energy Flow Concept Check What is the equation for photosynthesis? + +  + Water + Carbon Dioxide + Energy  Sugar + Oxygen

9. Photosynthesis & Energy Flow Concept Check Where do consumers (heterotrophs) get their energy?

10. Photosynthesis & Energy Flow Concept Check Where do consumers (heterotrophs) get their energy? – From the food they eat!

11. Photosynthesis & Energy Flow Concept Check What happens to the energy available to an organism?

12. Photosynthesis & Energy Flow Concept Check What happens to the energy available to an organism? – MOST of the energy they use – SOME of the energy moves into the atmosphere as heat – 10% of the energy is stored in plant tissues

13. Photosynthesis: Storing energy from the sun in sugar

14. Photosynthesis: Releasing energy in sugar to power life

15. Cellular respiration:: Releasing energy in sugar to power life

16. Objective Compare and contrast photosynthesis and cellular respiration. By the end of class, students will be able to:

17. Cellular respiration takes place in mitochondria

18. Inputs of cellular respiration: sugar

20. Return to the warm-up What is aerobic exercise?

21. Inputs of cellular respiration: oxygen

22. Outputs of cellular respiration: energy

23. Outputs of cellular respiration: carbon dioxide Carbon Oxygen

24. Outputs of cellular respiration: water Oxygen Hydrogen

25. Equation of cellular respiration Sugar + Oxygen  Energy + Carbon Dioxide + Water + +  + INPUTSOUTPUTS

26. What is the relationship between the equations for photosynthesis and cellular respiration?

27. Who uses cellular respiration?

28. Every organism with access to oxygen – Animals AND Plants

29. Fermentation is less efficient – (less energy per molecule of sugar) Organisms without access to oxygen break down sugar for energy by fermentation

30. Fermentation results in alcohol or lactic acid

31. Humans can use fermentation during anaerobic exercise Lactic acid in your muscles makes you sore

32. Muscles specialized for aerobic and anaerobic activity explain dark and light meat in turkey. http://www.slate.com/articles/life/the_spectator/2010/11/the_unbearabl e_whiteness_of_white_meat.html

33. Compare and contrast photosynthesis and cellular respiration

34. Exit ticket How are the outputs (products) of photosynthesis related to the inputs (reactants) of cellular respiration?
