1. Utilizing macerated flight muscle isolated from the fly, Calliphora sp, Wanzemann and Buzz report the production of approximately 20 moles of ATP for every mole of pyruvate completely degraded to CO2 and H20. In the same study the authors also conclusively demonstrate the presence of the Krebs Cycle and an electron transport system similar to the one found in other cells (1969 Acta Artifacta 239:316-332).
A. (6 pts) Suppose a pulse-labeling experiment were performed with the
macerated tissue using 14C- succinate (every carbon labeled).
What compounds would you expect to contain the label initially? after
30 minutes? Why? B. (8 pts) Draw a section of an inner mitochondrial membrane, illustrating
the components of the electron transport system and the flow of electrons
during the NAD and FAD oxidation. |
