Transcript of "Cellular respiration powerpoint unit 5 continued (revised2006)"

  1. 1. PROPERTIES OF LIFE WE HAVE ALREADY DISCUSSED CELLS REPRODUCTION METABOLISM- USE OF ENERGY HEREDITY RESPONSIVENESS GROWTH AND DEVELOPMENT INTERNAL BALANCE
  2. 2. NOW WE CONTINUE TO FOCUS ON METABOLISM- USE OF ENERGY
  3. 3. <ul><li>Who remembers the formula </li></ul><ul><li>for Photosynthesis? </li></ul>Write down the formula on your study guide using words, symbols or both.
  4. 4. The Relationship Between Photosynthesis and Cell Respiration <ul><li>Fill out as much as you know with your table partner! </li></ul><ul><li>Do it NOW! </li></ul><ul><li>Word Bank: </li></ul><ul><li>Autotrophs/Heterotrophs ATP </li></ul><ul><li>Cytoplasm/Mitochondria CO 2 & H 2 O </li></ul><ul><li>Chloroplasts in Plants Cells Functioning </li></ul><ul><li>The Sun’s Energy Glucose </li></ul><ul><li>Autotrophs </li></ul>
  5. 5. PHOTOSYNTHESIS IN TO COMBINE TO MAKE Which is used for USES PROCESS DONE BY CELLULAR RESPIRATION RELEASES PROCESS DONE BY IN THAT IS USED FOR PRODUCES RELATIONSHIP BEWTEEN PHOTOSYNTHESIS AND CELL RESPIRATION     AUTOTROPHS CHLOROPLASTS IN PLANTS THE SUN”S ENERGY CO 2 and H 2 O GLUCSOSE AUTOTROPHS & HETEROTROPHS Cytoplasm/ mitochondria ATP CELLS FUNCTIONING
  6. 6. Now that we have the food… Photosynthesis makes food right? What is that food? GLUCOSE But once the glucose is made, it needs to be transferred into a more useful form. It needs to go from food energy to cellular energy. We call this energy ATP and the process defined as: When an organism breaks glucose and transfers glucose energy into cell energy (ATP). Is called CELLULAR RESPIRATION
  7. 7. Cellular Respiration Formula <ul><li>The formula for cellular respiration is… </li></ul><ul><li>Glucose + O 2  CO 2 + Water + ATP </li></ul><ul><li>Hmmmm… that looks familiar, doesn’t it? Well it should… WHY????? </li></ul>BECAUSE IT IS THE OPPOSITE OF PHOTOSYNTHESIS
  8. 8. Cellular Respiration <ul><li>What does cellular respiration produce? </li></ul><ul><li>ATP </li></ul><ul><li>What is ATP? </li></ul><ul><li>A Molecule that transfers ENERGY!!! </li></ul><ul><li>What organisms perform cellular respiration? </li></ul><ul><li>Cells. Duh. </li></ul><ul><li>Seriously though, all cells use respiration- plants, animals, fish, bugs, fungi etc. </li></ul>
  9. 9. TABLE PARTNER THINKING: “Cellular Respiration & Photosynthesis” <ul><li>Write in the space provided similarities and differences of cellular respiration and photosynthesis. How do you think they relate?!?! </li></ul><ul><li>Also: Think about what </li></ul><ul><li>you think cells use ATP for. </li></ul>
  10. 10. PHOTOSYNTHESIS CELLULAR RESPIRATION BOTH ATP can be used to power such cellular reactions as active transport and protein formation.
  11. 11. 2 Stages of Cell Respiration: <ul><li>Step 1: Glycolysis- produces 2 ATP </li></ul><ul><li>Step 2: Aerobic (with oxygen)- 36 ATP </li></ul><ul><li>OR </li></ul><ul><li>Anaerobic (without oxygen)-No additional ATP made </li></ul>
  12. 12. Cell Respiration: Step 1- Glycolysis <ul><li>Glucose (produced by ________) is a 6-Carbon molecule. </li></ul><ul><li>Glycolysis (occurs in the cytoplasm), using ATP to change Glucose into two 3-Carbon molecules called pyruvate , when the pyruvate is formed this also produces 2 ATP! </li></ul><ul><li>and… 2 ATP molecules! </li></ul>2 1 3 4 5 6 1 Glucose Molecule 1 2 3 1 2 3 2 Pyruvate Molecules photosynthesis ATP ATP + = Carbon Atom
  13. 13. MINI REVIEW Glycolysis (Step 1) <ul><li>Where does glycolysis occur? </li></ul><ul><li>Cytoplasm </li></ul><ul><li>Glycolysis converts ________ to _______. </li></ul><ul><li>Glucose to Pyruvate </li></ul><ul><li>How many Carbons does Glucose have? Pyruvate? </li></ul><ul><li>6 for Glucose; 3 for Pyruvate </li></ul>
  14. 14. Step 2 of Cell Respiration: 2 Options <ul><li>Two options for using the pyruvate (sometimes called pyruvic acid) </li></ul><ul><li>made in glycolysis </li></ul>Option 1: Without oxygen Option 2: With Oxygen
  15. 15. Step 2 of Cell Respiration: <ul><li>Option 1: Anaerobic respiration (without oxygen- “anti aerobic”) </li></ul><ul><li>IN THE CELLS CYTOPLASM </li></ul><ul><li>Anaerobic is also called Fermentation </li></ul><ul><li>occurs when there is NO OXYGEN </li></ul><ul><li>No more ATP is formed. </li></ul>
  16. 16. ANAEROBIC RESPIRATION AKA FERMENTATION <ul><li>WHEN IT OCCURS IN PLANTS </li></ul><ul><li>ALCOHOL </li></ul><ul><li>is produced from the pyruvate . </li></ul><ul><li> This is what brewers use for beers! Have you heard of Beer fermentation? </li></ul><ul><li>WHEN IT OCCURS IN ANIMALS </li></ul><ul><li>LACTIC ACID </li></ul><ul><li>is produced from the pyruvate . </li></ul><ul><li>Many athletes know about this substance and its side effects- cramps/soreness </li></ul>
  17. 17. Clothespin… <ul><li>Squeeze your clothespin for one minute solid… on you mark… get set…. GO!!! </li></ul><ul><li>Why are your fingers tired? What do you think that has to do </li></ul><ul><li>with lactic acid? What </li></ul><ul><li>does it have to do with </li></ul><ul><li>cellular respiration? </li></ul>                     
  18. 18. Step 2 of Cell Respiration: <ul><li>Option 2: Aerobic Respiration (with oxygen) </li></ul><ul><li>A whopping 36 ATP molecules are formed with this method! </li></ul><ul><li>Takes place in the mitochondria , with a complex series of </li></ul><ul><li>chemical reactions </li></ul><ul><li>called the Krebs Cycle . </li></ul>
  19. 19. Aerobic Cellular respiration Produces the Most Energy! <ul><li>Remember Aerobic means with oxygen. For example: A erobic exercise is exercise that requires sustained amounts of Oxygen for long periods of time. </li></ul>Gosh, I look good.
  20. 20. Were you tired? Your cells might be <ul><li>To gain some appreciation for the amount of cellular energy needed to perform life functions consider the following: </li></ul><ul><ul><li>Each cell in the human body used between 1 to 2 million ATP molecules each minute. </li></ul></ul><ul><ul><li>Now multiple that by the fact that you have 100-150 trillion cells in your body.That ends up being one heck of a lot of ATP! </li></ul></ul>
  21. 21. <ul><li>In review… </li></ul>
  22. 22. 2 Stages of Cell Respiration: <ul><li>Step 1: Glycolysis- 6 Glucose split and converted to Pyruvate… producing a small amount of ATP (2 molecules). </li></ul><ul><li>Step 2: Aerobic (with oxygen)- pyruvate is used to make large amounts of ATP (36 molecules) in the mitochondria . </li></ul><ul><li>Anaerobic (without oxygen)- pyruvate converted into either lactic acid or ethanol in the cytoplasm , no more ATP. </li></ul>
  23. 23. The Basics of Cell Respiration <ul><li>Step 1: </li></ul><ul><li>(This step is glycolysis!) </li></ul><ul><li>Step 2: (Anaerobic- (Aerobic- with oxygen) </li></ul><ul><li>no oxygen) </li></ul>Glucose In cytoplasm Pyruvate 2 ATP Ethanol & CO 2 or Lactic Acid Mitochondria 36 ATP In Cytoplasm
  24. 25. Just so you know…
  25. 26. LAB TIME How might cells and cellular respiration be affected by a temperature change? What happens when you workout? Sweat, breath heavier, heart rate goes up, etc. Why? Because your muscle cells are working harder! They are respiring just like you!
  26. 27. LAB TIME Let’s test this out on other cells Does anyone remember how we measured the rate of photosynthesis in our last experiment? So, who has an idea of how we can measure the rate of cellular respiration? We counted the number of oxygen bubbles
  27. 28. LAB REVEALED Hopefully you figured out that… As temperature increases… cellular respiration increases! A formula called the Q10 coefficient says: For every 10 degree increase in temperature, the rate of respiration doubles!
  28. 29. Before we end… Is there anything you want to add to your Venn Diagram?
  29. 30. The Basics of Cell Respiration <ul><li>Step 1: </li></ul><ul><li>(Glycolysis) </li></ul><ul><li>Step 2: </li></ul><ul><li>(Anaerobic- (Aerobic- no oxygen) with oxygen) </li></ul>_ ATP __ ATP
