Cellular Respiration 1 Define oxidation and reduction 2 Describe the cellular regions where glycolysis the Krebs cycle Citric acid cycle and the electron transport chain occur 3 Describe how the carbon skeleton of glucose changes as it proceeds through glycolysis In general what happens to a glucose molecule as is proceeds through glycolysis 4 Describe where pyruvate is oxidized to acetyl CoA what molecules are produced and how this process links glycolysis to the Krebs cycle Citric acid cycle 5 Describe the role of NAD and the electron transport chain during respiration 6 Explain how the energetically favorable slide of electrons down the electron transport chain is coupled to the energetically unfavorable production of ATP by chemiosmosis 7 Describe the process of chemiosmosis 8 Summarize the net ATP yield both direct and indirect from the oxidation of one glucose molecule be sure to include the different stages of cellular respiration 9 Explain why fermentation is necessary 10 Compare the fate of pyruvate in alcohol fermentation and lactic acid fermentation 11 Compare the processes of fermentation and cellular respiration 12 Describe how food molecules other than glucose can be oxidized to make ATP what molecules and where do they enter the pathway
