Presentation Transcript

  1. Describe 5 ways in which photosynthesis is similar to cellular respiration. • What is the purpose of Oxygen in Aerobic Respiration? Warm Up 11/13

  2. Aerobic Respiration 2 ATP from glycolysis 2 ATP from Kreb’s Cycle 34 ATP from ETC (chemiosmosis) 38 ATP Made In Total - 2 ATP for transporting pyruvic acid into the Mitochondria from Glycolysis 36 Net ATP Made Aerobic Respiration is 20 times more efficient than Glycolysis alone.

  3. Fact: Our bodies uses ATP at the rate of about 1 million molecules per cell per second. There are more than 100 trillion cells in the human body. That’s about 100,000,000,000,000,000,000 ATP molecules used in your body each second!

  4. The Anaerobic Pathway Chapter 7: Cellular RespirationFermentation

  5. Fermentation = Glycolysis + Anaerobic pathway Occurs when there is no oxygen present Occurs in the cytoplasm Fermentation

  6. Lactic Acid Fermentation Alcoholic Fermentation Two types of Fermentation

  7. ● Pyruvic Acid from glycolysis is converted into another 3 carbon compound, Lactic Acid ● The process uses NADH converting it into NAD+ ● Muscle cells may produce Lactic Acid during strenuous exercise causing fatigue and pain ● Certain Bacteria and Fungi are used to ferment milk into cheese, buttermilk, yogurt, sour cream and other cultured dairy goods.

  8. Pyruvic Acid is converted into ethyl alcohol and CO2 • The process uses NADH converting it into NAD+ • NAD+ is then used to power glycolysis

  9. Performed by plant cells and unicellular organisms like Yeast • This process is also used in Bread-making • CO2 makes the bread rise & the alcohol evaporates during cooking The Alcohol Industry uses this process to make different beverages ● If the CO2 is allowed to escape = wine ● If the CO2 is kept in the liquid = sparkling wines or champagne

  10. Fermentation vs. Cellular (aerobic) Respiration Fermentation = Glycolysis + Anaerobic pathway ● Cellular (aerobic) Respiration = Glycolysis + Aerobic pathway ● produces 2 net ATP (from glycolysis) ● produces 36 more ATP ● recycles NADH made in Glycolysis into NAD+ ●Kreb’s Cycle makes energy to power ETC ● Recycled NAD+ keeps Glycolysis going ●ETC uses chemiosmosis to make ATP ● Occurs in the cytoplasm ● Occurs in the mitochondria ● Goal: keep Glycolysis going in order to make 2 ATP ● Goal: Make a lot of ATP!

  11. Turn in warm-ups 10/25-11/13 • Homework: • Photosynthesis & Cellular Respiration • Due Monday • Study Guide • Due Tuesday • Exam • Wednesday Assignments

  12. Title the next page Thinking Maps • Create a tree map for cellular respiration • Create a double bubble for each of the following: • Fermentation vs. cellular (aerobic) respiration • Lactic Acid Fermentation vs. Alcoholic Fermentation

  13. Add Words to your vocabulary chart • Fill out Cellular Respiration Chart • Summary and 5 things • SG #10-14
