  1. 4.4 Intro to Cellular Respiration 2.1 Atoms, Ions, and Molecules • Set up Cornell Notes on pg. 47 • Topic: 4.4/4.5 Intro to Cellular Respiration • Essential Question: 1. Describe the relationship between cellular respiration and photosynthesis in a double-bubble map. 1. Describe the relationship between cellular respiration and photosynthesis in a double bubble map.

  2. KEY CONCEPT The overall process of cellular respiration converts sugar into ATP using oxygen.

  3. Try and hold your breath for as long as you can (no cheating). How did you feel as you were holding your breath? Why do you think you felt this way? If you were to run a few miles, what would happen to your breathing?

  4. How does your body use oxygen? • Oxygen helps your body break down chemical energy that is stored in sugars and other carbon based molecules. • The energy produced is ATP ATP

  5. Pg. 46 Compare the reactants and products. What do you notice?

  6. Plants use photosynthesis to make their own food • Animals eats other organisms as food • Food is not the direct source of energy • Instead we break down molecules from food to produce ATP • Cellular respiration releases chemical energy from sugars (produced by photosynthesis) and other carbon-based molecules to make ATP when oxygen is present

  7. Two “Stages” • Light Dependent- ETC-Fuels Light Independent • Light Independent- Calvin Cycle- Makes Glucose • Two “Stages” • Stage I- Kreb’s Cycle- Fuels Stage II • Stage II- ETC- Makes lots of ATP!

  8. Cellular respiration takes place in mitochondria “the powerhouse of the cell”

  9. There are two main parts to a mitochondria: 1. Inner membrane 2. Matrix- area inside the inner membrane

  10. 1 2 3 4 Glycolysis: 1. 3. Takes place in ___________ 2. 5. 4. 6. 7. 8. Takes place in the _____________

  11. 1 2 3 4 Glycolysis: Glucose is broken down into 2 3-carbon molecules 1. Mitochondria ATP 3. Kreb’s Cycle Takes place in the Matrix 5. Energy 2. 2 Pyruvates 4. 6 CO2 Energy from Glycolysis ATP 6. 6 O2 7. 6 H2O 8. Electron Transport Chain Takes place in the Inner Membrane

  12. The equation for the overall process is: C6H12O6 + 6O2  6CO2 + 6H2O + ATP • The reactants in photosynthesis are the same as the products of cellular respiration.

  13. Glycolysismust take place first. It happens in the cell’s cytoplasm • anaerobic process (does not require oxygen) • splits glucose (from photosynthesis) into two three-carbon molecules called pyruvates • produces two ATP molecules 2 pyruvate “Sweet Split” ATP

  14. Cellular respiration releases chemical energy from glucose (produced by photosynthesis) and other carbon-based molecules to make ATP when oxygen is present • Cellular respiration is aerobic, or requires oxygen. O2

  16. Pg. 46 in INB Pg. 115 in book Cellular Respiration …..Reactants….. Stage 1 Stage 2 1. 2. 3. 4. …..Products…..

  17. 1 ATP mitochondrion matrix (area enclosed by inner membrane) and 6CO 2 energy 2 3 energy from glycolysis ATP inner membrane and and 6H O 6O 2 2 4 Stage I • The Krebs cycle takes place inthe mitochondrial matrix • 2 pyruvates enter cellular respiration • Pyruvates are broken down and ATP is made during the Kreb’s Cycle • ATP transfers energy-carrying molecules to Stage II: The Electron Transport Chain • releases carbon dioxide as waste Krebs Cycle

  18. 1 ATP mitochondrion matrix (area enclosed by inner membrane) and 6CO 2 energy 2 Electron Transport 3 energy from glycolysis ATP inner membrane and and 6H O 6O 2 2 4 Stage II • The electron transport chain produces a large amount of ATP and takes place in the inner membrane • 3. energy transferred to proteins in the inner membrane • 4. oxygen enters process and is used to make H2O • A large number of ATP molecules are produced • water and heat are released

  19. Cellular Respiration Sugar (2 pyruvates) O2 …..Reactants….. Stage 1 Stage 2 E.T.C.: Energy is transferred to proteins in the inner membrane of the mito. Energy is transferred to the E.T. C. A large # of ATP is made. O2 is used to make H2O The Kreb’s Cycle breaks down pyruvates into ATP H2O CO2 Heat …..Products…..

  22. Photosynthesis & Cellular Respiration 2.1 Atoms, Ions, and Molecules • Set up Cornell Notes on pg. 49 • Topic: Photosynthesis & Cellular Respiration • Essential Question: • What is the difference between aerobic and anaerobic processes. • What processes in cellular respiration are aerobic? Anaerobic? • What is the difference between aerobic and anaerobic processes. • What processes in cellular respiration are aerobic? Anaerobic?

  23. EQ: Please create a Double-bubble map comparing and contrasting Photosynthesis and Cellular Respiration. Pg. 48 in INB Cellular Respiration Photosynthesis Include: Reactants/Products, organisms that undergo each, Organelles, chemical equation, etc…

  24. White board: Cellular Respiration Photosynthesis

  25. Reactants • Light Energy • CO2 • H2O • Reactants • Glucose • O2 Plants Kreb’s Cycle Energy ATP Cellular Respiration Photosynthesis Mitochondria Chloroplast Animals Calvin Cycle Chemical Reactions • Products • CO2 • H2O • Heat • Products • Glucose (sugar) • O2 E.T.C ATP 2 Main Stages

  26. Two “Stages” • Light Dependent- ETC-Fuels Light Independent • Light Independent- Calvin Cycle- Makes Glucose • Two “Stages” • Stage I- Kreb’s Cycle- Fuels Stage II • Stage II- ETC- Makes lots of ATP!

  27. Life on Earth is solar powered, and energy makes a one-way trip through an ecosystem • Chemicals, however, are recycled • The CO2 and H2O released by cellular respiration are converted through photosynthesis to glucose and O2, which are then used again in respiration Photosynthesis CO2 and H2O Glucose and O2 • Cellular respiration
