Intro Bio I (BIO 311C), Fall 2009, Dr. Bushart Homework #7 1. One carbon is removed from pyruvate during its processing into acetyl-CoA, why is this not detrimental to the amount of energy gained by the citric acid cycle? 2. What is the minimum number of “turns” of the Kreb’s cycle necessary to completely oxidize the carbons from one (1) molecule of glucose? Explain your reasoning. 3. During heavy exercise O 2 is depleted along with ATP. Besides the general idea of “backup” stopping the full processing of glucose, how does enzymatic regulation play a role in the switch from respiration to fermentation? 4. Unlike how it was depicted in the BioFlix movie shown in class, pyruvate transport into the matrix space of mitochondria requires a proton (H + ) gradient. a. Explain the energetics and mechanics of this process. b. What impact does this have on the amount of ATP produced through oxidative phosphorylation? 5. A classic experiment involved placing isolated mitochondria in various solutions

    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.
