Presentation Transcript

  1. Concept 1: Analyzing the Processes of Cellular Respiration. Refer to pg 77-82 in Holtzclaw, Ch 9 in Campbell and media resources Refer to pg 300-303 in Holtzclaw, Inv 6 in LabManual Unit 4: Cellular Respiration and Photosynthesis

  2. Concept 1: From the lab… You must know… • The equation for cellular respiration. • The components of a repirometer and how they interact • The gas laws that affect volume changes within the repirometer and cellular respiration • The effect of temperature or increased metabolic activity on respiration • How to calculate the rate of respiration Read lab manual and p. 300-303 in Holtz Do #1-6 p. S73 in manual and #1-4 p. 303 in Holtz

  3. Concept 1: You must also know… • The summary equation of cellular respiration. • The difference between fermentation and cellular respiration. • The role of glycolysis in oxidizing glucose to two molecules of pyruvate • The process that brings pyruvate from the cytosol into the mitochondria and introduces it into the citric acid cycle • How the process of chemiosmosis utilizes the electrons from NADH and FADH2 to produce ATP

  4. An Overview – Go Over Charts!

  5. C6H12O6 + 6 O2 6 CO2 + 6 H2O + Energy (ATP + heat) Where can you find all of these reactants/products?

  6. C6H12O6 + 6 O2 6 CO2 + 6 H2O + Energy (ATP + heat) Where can you find all of these reactants/products?

  7. Overall route of electrons: What is the overall route of electrons during cellular respiration?

  8. Overall route of electrons: What is the overall route of electrons during cellular respiration?

  9. Try This! • If a person was not eating any glucose (or other carbohydrates than can be digested to glucose) in their regular food intake, what would happen to the ATP production in that person?

  10. Try This! • There would be no change in ATP production. • There are A LOT of biochemical pathways in your body that can convert one type of biological molecule to another. • Ex: amino acids to glucose

  11. Fermentation

  12. Fermentation

  13. First week in January… • PROJECTS!!! • Individual or in partners • See criteria and videos • Mon/Wed – Time to work • Fri – DUE 

  14. ACT OUT!
