Biology 100 Chapter 9- Electron Transport Chain Name: George Fountain III Group Name: Golden Retrievers Section: 7 Date: October 7, 2009 1. Where do the electrons in the ETC come from? Electrons are donated by the NADH and FADH2. 2. Fill in the blanks: In the ETC, the _electron_ is positively charged relative to the __reaction_. 3. What is the “real” job of the electron transport chain? H + ions are used to produce adenosine triphosphate (ATP), the main energy intermediate in living organisms. 4. Why is electronegativity important in the ETC? What is important about the electronegativity of oxygen? This is because oxygen is being used with hydrogen atoms. Oxygen is the final electron acceptor. 5. Draw and describe the ATP synthase complex. What is its function? The ATP synthase complex is when an enzyme that can synthesize adenosine triphosphate (ATP) from adenosine diphosphate (ADP) and inorganic phosphate by

Oxidative phosphorylation is a metabolic pathway that uses energy released by the oxidation of nutrients to produce adenosine triphosphate (ATP). Although the many forms of life on earth use a range of different nutrients, almost all carry out oxidative phosphorylation to produce ATP, the molecule that supplies energy to metabolism. It produces a high efficient rate of releasing energy. 7. Summarize fermentation. Draw a diagram. Fermentation is the process of deriving energy from the oxidation of organic compounds, such as carbohydrates, using an endogenous electron acceptor, which is usually an organic compound. 8. What is the most important result of fermentation? Glycolysis and the reduction of pyruvate...
