Problem set 4: http://www.davincipress.com/metabmelodies.html All problems are assigned from the 6 th edition of biochemistry by Stryer et al. Chapter 16: Glycolysis Pg. 473-474 2, 4, 7, 9(a,b,d), 13, 14, 15 (toughy) Note: #2 is a toughy and is a lot of work for a one word answer... but if you can answer it, you probably have a good grasp of the material. #4 requires data from table 16.1, page 444-445 Also, try this: Given the following reversible reaction: a) Identify A and B , as well as the enzyme that catalyzes this reaction (no peeking now… you can’t peek during the exam). b) What is the significance of this reaction? When would it occur (give an example)? c) Suppose the Δ G o’ of the above reaction is -25 kJ/mole. What is the highest ratio of products to reactants that would allow this reaction to go forward in the cell? d) There are some very rare cases where the enzyme catalyzing the above reaction is mutated and inactive. These patients suffer from exertional myoglobinuria (the presence of myoglobin in the urine during exercise) and fatigue upon heavy exercise. Explain these symptoms (hint: Where is myoglobin normally found?).

    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.
