Sping 2004 BCHS 3304 Exam III Review- 1). How many different stereoisomers are possible for a 5-carbon ketose sugar? a). 2 b). 4 c). 8 d). 12 e). 16 : (b), there are 2 (5-3) stereoisomers for a 5-carbon ketose sugar. 2). A healthy living cell maintains an overall thermodynamic value such that: : (e), a healthy living cell maintains an overall thermodynamic value such that G ° ’ < 0. 3). For the reaction catalyzed by adenylate kinase: ATP + AMP  2 ADP The overall G ° 0 even though the cellular [AMP], [ADP], and [ATP] are far away from their equilibrium values. What is an alternative explanation for why this reaction operates with a G ° 0? : (d), there is no net synthesis of high-energy phosphoanhydride bonds, they are only being rearranged. 4). What happens if you add more enzyme to an enzyme-catalyzed reaction already operating at V max ? a). K M will decrease. b). No change. c). Observed rate will be faster. d). k cat will increase. e). Observed rate will be slower.

: (c), the observed rate of reaction will be faster. 5). Which two answer choices are not characteristics of a committed step of a metabolic pathway? : (b) and (e) are not characteristics of metabolic pathways. 6). In enzyme catalysis, the proximity effect refers to: a). The effective increase in the concentrations of the reacting species by binding to the enzyme active site. b). The approach of a substrate to an enzyme. c). Close contacts made by neighboring enzyme monomers. d). The increase in energy produced by bringing two or more reactants into van der Waals contact. e). All of the above. : (a), the effective increase in the concentrations of the reacting species by binding to the enzyme active site.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    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.
