  1. Monday 17 OctoberTopic: Cellular Respiration DO NOW: Brainstorm everything that you can about energy. Think about things such as where it comes from, how it becomes available, how does it change into other forms, what is it used for, what types there are, etc. HW: • 8-1 Reading for Understanding

  2. Objective • By the end of this class, you will be able to write the chemical equation for cell respiration and identify its reactants and products. Agenda • Notes on cell respiration

  3. Why do we need energy? • Heterotrophs and Autotrophs • The ability to do work • To live • To power functions in the cell • To do your homework (muscle fiber, thinking) • To move

  4. In what form is energy available? • Solar energy • Electric energy • Kinetic • Chemical • Potential • Nuclear

  5. How does our body convert this energy? • ENERGY MUST BE AS ATP • Adenosine Tri-phosphate • We do not eat ATP • The mitochondria makes it with metabolism • What it takes in is called reactants • Products come out of a reaction

  6. Where do the waste products go? • There are two waste products • #1- Carbon dioxide-exhaling • #2- Water-urinating, sweating, and exhaling

  7. THE FORMULA!!! • O2+ C6H12O6 CO2 + H2O + ATP

  8. Tuesday 18 OctoberTopic: Measuring energy in food DO NOW: Pick up a lab packet from the kidney table and complete the pre-lab assignment HW: • Post-lab analysis questions

  9. Objective • Identify 3 similarities and 2 differences between cell respiration and burning food. • Calculate the number of calories in a Frito Agenda • Lab protocol • Demo of burning food • Labs part 1 & II

  10. Lab Protocol • All bags/excess paper/etc must be off the lab tables • Any hair long enough is to be tied back • During the burning portion, absolutely no getting up for anything (wait until after this portion of the lab is complete) • Identify 3 similarities and 2 differences between cell respiration and burning food. • Calculate the number of calories in a Frito

  11. FRONT OF ROOM AND INDIVIDUAL DESKS HERE! Maximo Mariam Guerschom Ania William Nellie Charlie Mark Damarys Marquise Noah A’Shaun Gizela Lowre Nahum Hazel Jaleel Stephanie Vilmari Cristian Nicole Antonio Isaiah Uriel Alondra Isaac Shreena Joas

  12. If you’ve finished… • Part I (burning food) of the lab • Complete the table on pg 1 • Write the analysis comparing and contrasting burning food to cell respiration • Part II (measuring calories) • Make sure all your data is filled in • Both parts of the lab • Make sure all lab pieces are in the metal tray • Start on the remainder of the analysis questions • Identify 3 similarities and 2 differences between cell respiration and burning food. • Calculate the number of calories in a Frito

  13. Thursday 20 OctoberTopic: Exercise, Cell Respiration, and your body DO NOW: Pick up a packet from the kidney table and complete the front page (“pre-lab”). You should fill in the blanks and write hypotheses for how exercise affects the body. HW: • Reflections and conclusions questions • Study for quiz

  14. Objective • Explain how the chemical equation for cell respiration relates to breathing, and why we breathe harder during exercise. Agenda • Protocol for outdoor activity • How to measure a pulse • Outside activity!

  15. Pulse & Breathing rate • Everyone focus for a few seconds and note if your breathing is slow, medium, or fast (compared to how you normally breathe) • Next, find your pulse on your neck or your wrist and we will measure it for 15 seconds • Multiply this number by 4 to get beats/min (bpm)

  16. Before going outside… • You only need to bring your lab and a pencil and can leave everything else here • We go out the back stairs, out the door, and around to the crosswalk • Line up with your partner along the edge of the basketball court by the red stairs • Once everyone completes the activity, listen for me to say “Now” and “End” which will be the timed minute for pulse • Swap with your partner

  17. Friday 21 OctoberTopic: Cell Respiration Review & Quiz DO NOW: Get a clicker from the kidney table and review sheet Take out your notes on cell respiration HW: • Read 38-1 and take notes in your notebook • Think of a food/meal that contains carbohydrates, lipids (fats), and proteins. Write it down after your reading notes!

  18. Objective • By the end of this class, you will be able to apply knowledge of cellular respiration to answer short-answer and open-response questions on the quiz Agenda • Cell respiration review • Quiz

  19. 1. What do you call the starting materials in a chemical equation? 30 • Products • Ingredients • Reactants • Starters 23

  20. 2. What are the reactants incellular respiration? 30 • O2 and CO2 • O2 and Glucose • Glucose and ATP • CO2, H2O, ATP, and heat 23

  21. 3. What are the products incellular respiration? 30 • O2 and CO2 • O2 and Glucose • Glucose and ATP • CO2, H2O, ATP, and heat 25

  22. 4. What is the purpose of cellular respiration? Why is it important? 30 • To help us breathe • To make glucose for cells • To make ATP for cells • To take in oxygen and release carbon dioxide 22

  23. 5. The organelle where cell respiration takes place is the 30 • Nucleus • Lysosome • Chloroplast • Vacuole • Mitochondrion • Ribosome 23

  24. 6. Why do some cells have more mitochondria than other cells? 30 • The cells use more energy • The cells store more nutrients • The cells degrade more proteins • The cells divide more frequently 23

  25. 7. A poison that prevents cell respiration in mitochondria will affect the production of… 30 • ATP • Glucose • Oxygen • RNA 21

  26. 8. Choose the correct statement about photosynthesis and cell respiration: 30 • Both in same organelle • Both happen in all living things • P produces carbon dioxide, and CR uses carbon dioxide • P stores energy and CR releases energy 23

  27. 9. Which happens in the reaction on your paper? 30 • Energy from ATP is used to make glucose • ADP adds a high-energy bond to its structure • ADP is used to provide oxygen to a cell • Energy is stored in ATP for future use 0

  28. 10. Which conclusion is best supported by the graph? 30 • ATP production is independent of sugar • Amount of cell respiration is constant • ATP is only produced when sugar is above 4 g/L • Amount of cell resp. increases as sugar concentration increases 21

  29. Question 10

  30. Exercise Lab Review • Why does breathing rate increase during exercise (2 reasons)? • Why does heart rate increase during exercise? • Does the amount of cell respiration increase during exercise? Why or why not?
