Presentation Transcript

  1. Respiration

  2. Breaking Down the Definitions • Cellular Respiration • Glycolysis • Pyruvic Acid • NADH • Anaerobic • Aerobic Respiration • Fermentation • Lactic Acid Fermentation • Alcoholic Fermentation • Mitochondrial Matrix • Krebs Cycle • Oxaloacetic Acid • Citric Acid

  3. BrainPop Respiration

  4. Chemical Equation of Cellular RespirationQuiz Next Meeting! Cellular Respiration is the complex process in which cells make ATP by breaking down organic compounds

  5. 3 Stages of Cellular Respiration

  6. Glycolysis • Organic compounds are converted into 3-Carbon molecules of PYRUVIC Acid, making ATP and NADH (an electron carrier molecule). • Cash vs Check • In Cytoplasm • Anaerobic process • Produces 2 ATPs of Energy

  7. Glycolysis Aerobic Respiration New 3-Carbon Molecule Pyruvic Acid New 6 Carbon Molecule Sugars G3P Anaerobic Respiration

  8. If No Oxygen Present the Pyruvic Acid… • Anaerobic Process • Fermentation • Pyruvic acid is converted into NAD and NADH, creating Lactic Acid (muscle soreness, cramps, fatigue) • Some plants convert Pyruvic acid into ethyl alcohol

  9. If Oxygen is present the Pyruvic Acid • Continues into the KREBS Cycle • Also called Citric Acid Cycle • Occurs in the Mitochondria

  10. Krebs Cycle • Pyruvates with the help on an enzyme, Acetyl CoA, combine with Oxaloacetic acid to make Citric Acid and also releases CO2. • Citric Acid then release more CO2 and a Hydrogen atom to create a 5 Carbon molecule and NADH • The new 5 Carbon molecule release more CO2 and another Hydrogen atom to make a 4 Carbon molecule and NADH • The 4 Carbon molecule releases another H and also FAD • The 4 Carbon molecule releases another H and forms Oxaloacetic Acid and the Krebs cycle continues

  11. Krebs Cycle

  12. Electron Transport Chain (ETC) • All of the FADs and NADHs created in Krebs Cycle give there electrons to the ETC • ETC ultimately produces ATP, up to 34 molecules!

  13. Efficiency of Cellular Respiration • 1 Molecule of Glucose yields • 34 molecules of ATP from ETC • 2 molecules of ATP from Glycolysis • 2 molecules of ATP from Krebs cycle

  14. Crash Course Video-Respiration
