BCH4024 OC SP25 E3 Q2: Dr. Otto Warburg proposed that cancer cells have an altered metabolism, one that is much more reliant on glycolysis for ATP production, which explains their ability to grow and metastasize. In the 80 years since the “Warburg Hypothesis” was presented, we have learned a lot about the biochemistry of cancer. The following 6 questions are focused on these findings. The cancer cell’s increased dependence on glycolysis for its energy needs also implies that which of the following statements must also be true in a cancer cell?

If the equilibrium constant for A + B   C is 0.175, then the equilibrium constant for 2C   2A + 2B is

Consider the following reaction: CS 2(g) + 4H 2(g)   CH 4(g) + 2H 2S(g). The equilibrium constant K is about 0.27 at 900.°C. What is K p at this temperature?

Consider the chemical system CO + Cl2 COCl2; K = 4.6 × 109 L/mol. How do the equilibrium concentrations of the reactants compare to the equilibrium concentration of the product?

The questions below refer to the following system:   Co(H2O)62+ + 4 Cl– CoCl42– + 6H2O     (pink)            (blue) When cobalt(II) chloride is added to pure water, the Co2+ ions hydrate. The hydrated form then reacts with the Cl– ions to set up the equilibrium shown here. Which statement below describes the change that the system will undergo if silver nitrate is added?

Which of the following would require automatic referral today?
