Reaction\ ** For each reaction listed, know the following: - - - - - - a\) Light-dependent reaction -- photosystem I\ b) Light-dependent reaction -- photosystem II\ c) Dark reaction -- Calvin-Benson cycle\ d) Glycolysis\ e) Krebs (citric acid) cycle\ f) Electron Transport Chain (ETC) **3. General Concepts** - - - - - - - - - - **BIOLOGY 20\ ** **Cellular Respiration Quiz** 1. 2. - - - Record any other names these reactions could be known as. 3. 4. - - - - - - - 5. - - - - 6. - - 7. - - - CR 1,2 and 3 **Metabolic Pathways** - - Cellular respiration: The **PROCESS** by which cells break down high- energy compounds and generate atp How is stored energy released? And how is it stored? - So, how does ATP work? - Parts of the **mitochondria** - - Oxidation vs Reduction - - - → *Reducing power:* 1. 2. Electron carriers in Cellular Respiration - →NAD+ an electron carrier accepts electrons in cellular process - →FAD2+ an electron carrier that accepts electrons in cellular process A Redox Reaction During cellular respiration glucose is **oxidized** by losing electrons while oxygen is reduced by gaining electrons What are the three ways to release energy? 1. 2. 3. More info on aerobic respiration: It's a series of enzyme catalyzed reactions whereby electrons are transferred from glucose to oxygen to generate ATP What are the three steps to produce ATP 1. 2. 3. Glycolysis - - - - Summary of Glycolysis 3 products are produced: - - - Net: Glucose → 2 pyruvate + 2H2O 4 ATP formed + 2 ATP used → 2 ATP 2 NAD+ +4 electrons + 4 Hydrogens → NADH + 2 Hydrogens Fermentation - Fermentation use in Industry - - - Krebs Cycle Introduction Pyruvate enters mitochondria → loses a carbon atom to form CO2 → bonds with coenzyme A (CoA) to form acetyl CoA→NAD+→reduced to NADH Krebs Cycle - - - - Krebs Cycle Summarized: - - Electron Transport Chain - - - - - - Chemiosmosis Couples movement of hydrogens diffusing with the work of ATP synthase - Note: Oxygen is not required until the very [last step] of aerobic respiration, but is vital for the whole process!
