tailieunhanh - Lecture AP Biology - Chapter 9: Cellular respiration

This chapter explain in general terms how redox reactions are involved in energy exchanges; name the three stages of cellular respiration, for each, state the region of the eukaryotic cell where it occurs and the products that result; in general terms, explain the role of the electron transport chain in cellular respiration;. | Define: Glycolysis Respiration Chemiosmosis Phosphorylation Fermentation ATP (draw and label) Electrochemical gradient FAD FADH2 NAD+ NADH What is the role of phosphofructokinase? How does it “work”? Explain “glycolysis”. Where does it occur? How does it “work”? What is the chemical equation for cellular respiration? Remember: OILRIG In the conversion of glucose and oxygen to CO2 and H2O, which molecule is reduced? Which is oxidized? What happens to the energy that is released in this redox reaction? NAD+ is called a(n) _. Its reduced form is _. What is 1 fact you remember from yesterday’s sugar article? Why is glycolysis considered an ancient metabolic process? Where in the cell does glycolysis occur? What are the reactants and products of glycolysis? Here’s what! Summarize the main ideas in this article What is the research about? So what? Why is the research being conducted? What is the importance of this work? What is the data showing? Now what? What are the next steps? What do scientists hope to accomplish in the future with this information? Which has more energy available: ADP or ATP? NAD+ or NADH? FAD+ or FADH2? Where does the Citric Acid Cycle occur in the cell? What are the main products of the CAC? What are 3 ways respiration can be measured? What is the purpose of using KOH (potassium hydroxide) in this lab? What are the Independent and Dependent Variables for Graph How is the proton gradient generated? What is its purpose? Describe how ATP synthase works. Where are the proteins of the ETC located? Where does the ETC pump H+ ions into? In cellular respiration, how many ATP are generated through: Substrate-level phosphorylation? Oxidative phosphorylation? In fermentation, how is NAD+ recycled? You eat a steak and salad. Which macromolecule cannot be broken down to make ATP? Think about the structure of a fat molecule. What feature of its structure makes it a better fuel than a carbohydrate (like glucose)?
