  CELL BIOLOGY PROBLEM SET 9  1. What is "substrate-level" phosphorylation and how does it relate to glycolysis? 2. What cytoskeletal structure holds mitochondria in place?  What experiments might you  do to verify that it is indeed this structural element and not one of the other cytoskeletal  proteins? 3. What is the difference between facultative and obligate anaerobes? 4. How is the sodium/potassium pump indirectly related to the ability of cells to obtain  glucose from outside the cells? 5. What is NAD+ and why is it important to energy metabolism in the cell? 6. The mitochondrion can ship ATP out to the cytoplasm. But how do the component  substrates of ATP, namely ADP and pi, get into the mitochondria? 7. NADH is an energy-rich molecule synthesized in the cytoplasm but its energy can be  converted to ATP only in the mitochondrion. But NADH can’t diffuse into the matrix of  the mitochondrion. Explain this apparent paradox. 8. Rhodamine 123 is a fluorescent indicator dye useful for examining mitochondria. a. Why is it called a "vital" dye?
