Name KEY Respiration Workshop Part IV Cellular Respiration Problems A. Using the worksheets from Part I, II, and III of today’s lab, fill in the table below. Use the table to calculate the total number of ATP molecules produced per molecule of glucose. See NOTES below before beginning you calculations Pathway CO 2 NADH FADH 2 Net ATP made by substrate level phosphorylation ATP eventually made by oxidative phosphorylation From NADH From FADH 2 Glycolysis 0 2 0 2 2 X 1.5 = 3 0 Linking Step 2 2 0 0 2 X 2.5 = 5 0 Krebs Cycle 4 6 2 2 6 X 2.5 = 15 2 X 1.5 TOTALS 6 10 2 4 23 3 Net number of ATP molecules per molecule of glucose = 4 + 23 + 3 = 30 NOTES: Remember, if you know the # of molecules produced per molecule of pyruvate, then you will need to double the number when considering yield per molecule of glucose. For calculating ATP yield from oxidative phosphorylation: Each FADH 2 yields 1.5 molecules of ATP Each NADH generated in the cytosol yields 1.5 molecules of ATP Each NADH generated in the mitochondria yields 2.5 molecules of ATP Note: Be sure you know why the ATP yield from cytosolic NADH is lower than that of mitochondrial NADH!
