AP Bio Ch 6 Goals Cellular Respiration• Diagram the flow of energy through the biosphere.• Describe the overall summary equation for cellular respiration.• Explain why cellular respiration is exergonic.• List the 3 metabolic stages of cellular respiration.• Distinguish between substrate level phosphorylation & oxidative
phosphorylation.• Define oxidation & reduction, oxidizing agent & reducing agent.• Explain why glucose doesn’t spontaneously combust in our cells.• Explain the importance of phosphorylation.• List the 2 coenzymes involved in cellular respiration & explain their roles.• Explain the role dehydrogenases in the oxidation of glucose.• Write a summary equation for glycolysis & describe where it occurs in
the cell.• Explain why glycolysis alone is not efficient.• Describe the structure of the mitochondrion.• Describe where pyruvate is oxidized to acetyl CoA, what molecules are
produced, and how it links glycolysis to the Krebs cycle.• Describe the locations, molecules in and molecules out for the Krebs
cycle.
• Explain at what point during cellular respiration glucose is completely oxidized.
• Explain the composition, location and function of the electron transport chain.
• Describe the process of chemiosmosis.• Trace the path of electrons during aerobic respiration (cellular
respiration).• State what energy source most directly drives ATP synthesis during
respiratory oxidative phosphorylation.• Summarize the net ATP yield from the oxidation of a glucose molecule by
constructing a chart that shows how many ATP are produced at each stage of cellular respiration (both by substrate level phosphorylation and oxidative phsphorylation).
• Describe the fate of pyruvate in the absence of oxygen.• Explain why fermentation is necessary.• Distinguish between aerobic and anaerobic metabolism.• Describe how food molecules other than glucose can be oxidized to make
ATP and state the type of food molecule that produces the most ATP per gram.
• Explain 3 reasons scientists believe that glycolysis is considered one of the first metabolic pathways to have evolved.
• Explain what role the allosteric enzyme phosphofructokinase plays in the control of ATP production in the cell.
