A lecture presentation of the processes of aerobic cellular respiration based on BSCS Blue and Campbell Biology.

1. Cellular Respiration: Energy for Life

3. Where Does Cellular Energy Come From? Sunlight Autotrophs Food ATP

4. Cellular Respiration Converts the Chemical Energy in Food into ATP

5. ATP is used as cellular energy currency Energy is released when ATP is converted to ADP

8. The Reactions of Cellular Respiration All living things require energy from food The primary energy molecule is glucose The Process of Cellular Respiration converts the energy in glucose into ATP for use by the cell

10. Complete Breakdown of Glucose is Aerobic Produces 36-38 ATP per Glucose

11. Glycolysis The “Glucose Splitting” reaction

13. The Krebs Cycle Intermediate Reactions

14. Intermediate Reactions Pyruvate converted to Acetyl CoA (enters Krebs Cycle) CO 2 is released NAD + is reduced to NADH

16. The Electron Transport System

18. Total ATP Production
