Draw a schematic for each pathway (see example below on left), and organize the pathways into flow diagram (see example below on right) to show how each is related to the other. Use a second sheet of paper or the back of this page if needed. In your schematics you should include the names of the following molecules: glucose, pyruvate, acetyl CoA, CO 2 , O 2 , H 2 O. No others are required. You do not need to include any of the carbon intermediates in the citric acid cycle or the specific proteins in the electron transport chain. In addition, your schematics should indicate 1) where ATP is generated and how much, 2) when NADH + H + and FADH 2 is produced, and 3) how NAD + and FAD + is regenerated. glucose pyruvate 2 ATP NAD + NADH + H + GLYCOLYSIS CO glucose ATP CALVIN CYCLE 2 NADP NADPH + H + + 3PG Glycerol + fatty acids lipids MEMBRANE BIOSYNTHESIS 3PG Name_____________________________________ Section_______ TA_____________ 2 Question 2 You are doing a genetics experiment with the fruit fly.
