Unformatted text preview: Name Respiration Workshop Part IV Cellular Respiration Accounting and Homework 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 ATP eventually made by oxidative phosphorylation Pathway CO 2 NADH FADH 2 ATP made by substrate level 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 Total 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 By the way, why do you suppose the ATP yield from cytosolic NADH ends up being lower than that of mitochondrial NADH? mitochondrial NADH?...
