3 points) Triacylglycerols contain three fatty acids esterified to glycerol. Compared to a su triacylglycerol, a triacylglycerol that has many cis-double bonds will: (choose one answer) a. Have a higher melting point b. Be more likely to form bilayers C. Form micelles d. All of the above e. None of the above 2. (8 points) True or False a. The net products of glycolysis are 2 ATP, 4 NADH, and 2 pyruvate molecules. b. Reaction 6 of glycolysis (glyceraldehyde 3-phosphate — 1,3 bisphosphoglycerate) is an reduction reaction c. Reaction 10 of glycolysis (phosphoenolpyruvate → pyruvate) produces 1 ATP per every produced d. Reaction 6 (glyceraldehyde 3-phosphate → 1,3 bisphosphoglycerate) requires the inve: 1 ATP. e. Reaction 3 (fructose 6-phosphate → fructose 1,6 biphosphate) is heavily regulated, incl regulation by fructose 2,6 biphosphate (F26BP). f. Under anaerobic conditions, the pyruvate produced in glycolysis is reduced to lactic acii NADH is oxidized to NAD & Under anaerobic conditions, the net products of the reactions going from glucose to lac are 2 ATPs. h. Under anaerobic conditions, it is important to oxidize NADH because glycolysis can only if NAD is available. 3. (4 points) Which of the following statements about the citric acid cycle are true? Mark true a. Pyruvate, the end product of glycolysis, enters the citric acid cycle after it has been conv lactic acid b. There are 2 steps in the citric acid cycle that generate CO2 C. There are 4 steps in the citric acid cycle that generate a reduced coenzyme (NADH or QH d. Acetyl-CoA can form glucose by entering the citric acid cycle because this increases the concentration of oxaloacetate, which can be converted to glucose 4. (3 points) Valine has pka values of 2.32 and 9.62. At PH 10.0 the most abundant form of vali net charge of: (choose one answer) a. +1 b. 0 C. -1 d. 2
