1 of 1 3. A sample of glucose reacts in anaerobic respiration. The right- hand box below shows a particle diagram of the moles of substances present after the reaction is complete. fe On a piece of paper draw the "Before" box as shown and draw a particle diagram of the reactant molecules that produced the mixture shown on the right. Key = C2H5OH = CO2 = CgH1206 Sub Before After You will need to draw a diagram to answer this question. On a piece of paper, draw the "Before" box as shown, and then draw a particle diagram of the reactant molecules that produced the mixture shown on the right. Upload an image of your drawing by clicking "Upload files" or by dragging and dropping your file into the box. Or, use your device's camera to take a photo of your work by clicking the camera icon.

7. Complete the following reactions: ( 关关 H H H OH H H NIC 8. Compare hydrolase and lyase enzymes. ( OH I + HO

Figure 1. + Η NaOH, H2O (pKa = 15) heat H + "Да H A pKa = 20 B pKa = 17 D The aldol condensation reaction in Figure 1 is an amazing example of how unfavorable equilibrium processes can be manipulated to generate product in good yields. In this case, the major product is the self-condensation product, D. The next most abundant product is the crossed aldol product, C. There are 2 other less favorable products that could form but are not shown in Figure 1. Draw a plausible electron pushing mechanism to show how product C is formed. Remember, if an alow Stans mom an electron pair, you must explicitly draw those electrons in.
