SI Worksheet #10 (Chapter 9) BY 123Meeting 10/8/2015Chapter 9: Write the overall reaction for cellular respiration.What is the literal meaning of glycolysis?Where in the cell does glycolysis take place?What is the advantage of glycolysis taking place stepwise?How many ATP are used (changed to ADP) in the first half of glycolysis?How many ATP are made from ADP in the second half of glycolysis?What is the net gain of ATP in glycolysis?How many molecules of pyruvic acid are made from a single molecule of glucose?What molecule stores the high-energy electrons (and hydrogen) removed from glucose in glycolysis? What is so special about step 3 in glycolysis? Does glycolysis need oxygen to occur?Glycolysis: Glucose ActivationDuring the first four steps of glycolysis, _____________ are transferred to ________________ via ___________________, where __________________ is converted to _______________. The end product is fructose 1, 6-bisphosphate. Sugar SplittingFructose 1,6-bisphosphate gets split into two fragments, dihydroxyacetone phosphate (DHAP) and glyceraldehyde 3-phosphate (G3P)._____________ then gets converted into _______________ by the enzyme __________________. OxidationBoth molecules of G3P become ______________ using __________________, which becomes ______________________. This process releases energy which is used to attach ___________________ to the sugars, making them 1,3-bisphosphoglycerate. Formation of ATPDuring the last four steps of glycolysis, the _______________________ groups of the molecules are transferred to _______________________ by the enzyme ________________________ creating _________________. This is done via the process of ________________________________. The three metabolic stages of cellular respirationGlycolysisCitric Acid CycleElectron Transport Chain and chemiosmosis: oxidative phosphorylationIn which step is most of the cell’s ATP produced? Where in the cell does the citric acid cycle take place?What must happen to pyruvate before entering the citric acid cycle? How does this process occur?Where does the oxaloacetate that Acetyl CoA combines with come from? What does this joining produce?What do the next 7 steps of the citric acid cycle do to citrate? How many ATP are generated per pyruvate?Fill in the table telling the energy rich molecules and amounts of each energy rich molecule produced in the citric acid cycle.Energy Rich MoleculeNumber producedWhere is the electron transport chain located in an eukaryotic organism? In a prokaryotic organism? How does the structure of the mitochondria allow space for thousands of copies of the electron transport chain?What are most of the components of the electron transport chain? How do these components exist within the chain? Electron carries alternate between ____________________ and _____________________ states as they accept and donate electrons. you move down the electron transport chain, each electron carrier becomes more________________ with the most electronegative carrier being ___________________________.Electrons are transferred from ______________________ to the first molecule in the electron transport chain in complex I.What are cytochromes?FADH2 adds electrons to ______________________ first.What is chemiosmosis?What is the structure of ATP synthase? What is the role of ATP synthase in chemiosmosis?_____________________________ and _____________________ enables cells to produce ATP without the use of oxygen.Can organisms living in environments without oxygen have electron transport chains? If so, how? What are the two type of fermentation discussed in this chapter? What is an obligate anaerobe?What is a facultative anaerobe? ................
