Unformatted text preview: = -7200J /mol + 12090)/m 3 of 6 = +4Boos / mal NAME Question 6. (3 pt.) Arsenate is a poison. It is a structural analog of phosphate, so it inhibits proteins that use inorganic phosphate as a substrate. What enzyme does it inhibit in glycolysis?_ glyceraldehyde3-Prophate dehydrogenase Question 7. (9 pts) Complete the following statements about glycolysis using terms from the list below. Some terms will not be used. 3-phosphoglycerate aldolase dihydroxyacetone phosphate enolase fructose-1,6-bisphosphate glyceraldehyde 3-phosphate lactate oxidative pyruvate phosphoenolpyruvate phosphofructokinase-1 substrate-level glucose 6-phosphate A. The end product of glycolysis is pyruvate B. The first committed step of glycolysis is catalyzed by phosphofructoknox - C. NAD+ is reduced in a reaction where erciderde 3-prespistoxidized. D. ATP is "invested" in two steps to make the 6-carbon sugars _lucasc lo-phosphate and _fructose lib biphosphate E. ATP is produced in glycolysis by substrate level phosphorylation. F. Aldolase splits a hexose into these two three carbon compounds: dihydroxyacetonephosphate and. glyceraldehyde 3- phosphate G. phosphoen.pyrovee is the substrate of the second ATP-yielding reaction. Question 8. (8 pts., 4 pts each) Draw the products of the reaction catalyzed by aldolase in glycolysis. CH 20- POS H-4=0 C=0 H - C - OH CHIOH CHOPO2 2 - W NAME Key Question 9. (2 pts) Which statement about gluconeogenesis is TRUE? A. All reactions of gluconeogenesis are the reverse of glycolysis reactions. B. Gluconeogenesis occurs in mammals but not in other types of organisms. C. The liver is the primary site of gluconeogenesis in humans. D. Only carbohydrate compounds are precursors for gluconeogenesis. Question 10. (5pts.) Rates of biochemical reactions can be affected by (circle all the correct answers) A. ) Concentration of reactants...

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
