  1. Respiration Day 1

  2. Saving for a Rainy Day Suppose you earned extra money by having a job. At first, you might be tempted to spend all of the money, but then you decide to open a bank account. • What are the benefits of having a bank account? • What do you have to do if you need some of this money? • What might your body do when it has more energy than it needs? • What does your body do when it needs energy?

  3. Cell Respiration) - YouTube ENERGY ATP: Adenosine Triphosphate • Stores chemical energy released from cellular respiration • ATP releases energy for life processes by losing one phosphate, forming ADP (Adenosine Diphosphate) • Energy released from food is stored by adding a phosphate to ADP, forming ATP

  4. Chemical Energy & Food • Calorie:energy needed to raise the temperature of 1 gram of water by 1 degree Celsius • Chemical energy stored in food (glucose) is released by breaking chemical bonds during cellular respiration

  5. ATP / ADP Cycle ATP ADP

  6. ATP / ADP Chemical Reactions ReactantsProducts ATP ADP + P ADP + P ATP Hydrolysis enzymes + Water + ? + Energy + ? Dehydration synthesis enzymes + Energy + ? + Water + ?

  7. Respiration Day 2

  8. Strongest Student Contest! Let’s see who can hold piles of textbooks for the longest period of time!

  9. Brainpop Cellular Respiration

  10. Cell Respiration • releases energy stored in the chemical bonds of food molecules, converting it to a useable form (ATP) • May or may not require oxygen (2 types) • occurs in the mitochondria and cytoplasm

  11. 2 types of Cellular Respiration • Aerobic Respiration (OXYGEN required!) Equation: • Yields a net gain of 36 ATP for each glucose molecule broken down • This energy is released a little at a time through a complicated set of reactions • Glycolysis (in cytoplasm) • Krebs Cycle • Electron Transport Chain Glucose Song

  12. Day 3 • Anaerobic Respiration / Fermentation

  13. 2) Anaerobic Respiration (a.k.a.Fermentation) • NO oxygen required • Produces only 2 ATP per glucose Why do it???? • Some types of cells lack the enzymes & organelles needed for aerobic respiration • When in short supply of oxygen, some animals will do it!

  14. A. Lactic Acid Fermentation • Produces lactic acid and 2 ATP • Performed by animal cells and some bacteria • Associated with muscle fatigue • Important in production of cheese & yogurt

  15. Equation:

  16. B. Alcoholic Fermentation • Produces alcohol, CO2, and 2 ATP • Performed by yeast (fungi) & bacteria (needed for baking, wine and beer making)

  17. Equation:

  18. Use these terms to complete the Respiration flowchart! • 2 ATP • O2 • CO2 • CO2 • Lactic acid • H2O • H2O • C6H12O6 • C6H12O6 • C6H12O6 • Alcohol • (aka “fermentation) • (uses oxygen) • ~36 ATP

  19. Day 4

  20. SATII Material (Cristae) – Electron Transport Chain! (Inner Membrane) Innermost section of the mitochondria (KREBS CYCLE!!)

  21. 2 molecules of pyruvic acid • NADH • 4ATP (net gain 2ATP!!) Anaerobic: uses no oxygen All do it! Glucose 2ATP for activation! “breaking glucose” Cytoplasm • CO2 • 8 NADH • 2 FADH2 Matrix (“KR”) Aerobic (needs O2) Oxygen 2 Pyruvic Acids Video Cristae (inner membrane) In some prokaryotes, occurs across the cell membrane • The most ATP!!!!! (34) • Water Aerobic (needs O2) (occurs in plants, animals, algae and some bacteria!) NADH FADH2 Oxygen (*final electron receptor!) Electron Transport System

  22. Evolved first! • Citric acid is constantly broken down and built up to produce high energy electron carriers!! (NADH and FADH2)
