BCH4024 OC SP25 E3 Q16: Refer to the picture below – Which of the following statements regarding the production of molecule B in this pathway is TRUE?

BCH4024 OC SP25 E3 Q28: Mitchell’s chemiosmotic theory suggested that a high concentration of protons outside the mitochondrial membrane:

BCH4024 OC SP25 E3 Q25: The next two questions relate to the following clinical scenario: Sparty has type 1 diabetes mellitus. His body is unable to produce insulin, and hence hormonal regulation associated with insulin is not observed.  He has just been admitted to the hospital with symptoms of Kussmaul respirations (rapid and deep breathing), polyuria (frequent urination) and polydipsia (frequent thirst). Initial lab data indicated elevated blood glucose, and the presence of glucose and ketone bodies in the urine.  At the time of Sparty’s admission to the hospital, which of the following conditions is most likely correct?

BCH4024 OC SP25 E3 Q44: Porphyria is an inherited condition that results in the failure to produce sufficient levels of porphyrins (see structure). Inability to produce sufficient porphyrins can have a devastating effect on cells to produce ATP by cellular respiration. What of the following would be directly and severely restricted in an individual with porphyria?

BCH4024 OC SP25 E3 Q27: A novel organism has been found with a unique electron transfer chain. The Eo values for the individual components are as follows: Component A = + 1.004 mv Component B = -0.027 mv Component C = +0.321 mv Component D = -0.064 mv Component E = -0.457 mv What is the likely order of the transfer of electrons in this chain?

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?

A list can be Array-based or Link-based.

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?

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