Cell respirationa

  1. 1. Monday 17 October Topic: Cellular RespirationDO NOW:• Brainstorm everything that you can about energy.Think about things such as where it comes from, how itbecomes 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. 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. 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. 4. In what form is energy available? Solar energy Electric energy Kinetic Chemical Potential Nuclear
  5. 5. How does our body convert thisenergy? 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. 6. Where do the waste products go? There are two waste products #1- Carbon dioxide-exhaling #2- Water-urinating, sweating, and exhaling
  7. 7. THE FORMULA!!! O2+ C6H12O6  CO2 + H2O + ATP
  8. 8. Tuesday 18 October Topic: Measuring energy in foodDO NOW:• Pick up a lab packet from the kidney table andcomplete the pre-lab assignmentHW:• Post-lab analysis questions
  9. 9. Objective Identify 3 similarities and 2 differences between cell respiration and burning food. Calculate the number of calories in a FritoAgenda Lab protocol Demo of burning food Labs part 1 & II
  10. 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. 11. FRONT OF ROOM AND INDIVIDUAL DESKS HERE! Maximo Mariam Guerschom AniaWilliam Nellie Charlie Mark Damarys A’Shaun Gizela Marquise Noah Lowre Nahum Hazel Jaleel Stephanie Vilmari Antonio Cristian NicoleIsaiah Uriel Alondra Isaac Shreena Joas
  12. 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 questionsIdentify 3 similarities and 2 differences between cell respiration and burning food.Calculate the number of calories in a Frito
  13. 13. Thursday 20 OctoberTopic: Exercise, Cell Respiration, andyour bodyDO NOW:• Pick up a packet from the kidney table and complete thefront page (“pre-lab”). You should fill in the blanks andwrite hypotheses for how exercise affects the body.HW:• Reflections and conclusions questions• Study for quiz
  14. 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. 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. 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. 17. Friday 21 OctoberTopic: Cell Respiration Review & QuizDO NOW:• Get a clicker from the kidney table and review sheet• Take out your notes on cell respirationHW:• 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 readingnotes!
  18. 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 quizAgenda Cell respiration review Quiz
