Unformatted text preview: Life Science 2 (lecture 6) I. Summary of Cellular Respiration II. Respiration is a redox process III. Glycolysis = "Splitting Sugar" IV. Citric Acid Cycle: Building high energy electron carriers V. Electron Transport Chain --> ATP Payoff-------------------------------------------------------------------- I. Summary of Cellular Respiration Big Picture: Sun -- Photosynthesis --> Glucose + O2 ---> Small Intestine ---> Blood ---> Glucose inside the cell -- Glycolysis (2 NADH + 2 APT) --> 2 Pyruvate 1. w/o O2: produce Lactic acid and NAD+ (to keep glycolysis running) 2. w/ O2: pyruvate goes into mitochondria matrix and start Citric Acid Cycle; inner mitochondria membrane to start ETC SUMMARY 1. Photosynthesis 2. Eating 3. Glucose Transporters 4. Glycolysis 5. Fermentation (w/o O2) 6. Citric Acid Cycle 7. Electron Transport & Oxidative Phosphorylation TAKE HOME MESSAGE #1: In cell respiration, food and oxygen are converted to CO2, H2O, and Energy (ATP)....
