Consider the following reaction: (P, is inorganic phosphate, i.e., HPO4² and H₂PO4) glucose + P + 3.3 kcal glucose-6-phosphate + H₂O If the energy used for the reaction is obtained from the hydrolysis of ATP (AH = -7.3 kcal.mol), the reaction will go to completion. Select one: O True O False

When the reaction below reaches equilibrium, does the equilibrium lie on the left or the right side?  Briefly explain. ClO–  +  CH3CO2H  ⇌  HClO  +  CH3CO2–   When the terminal phosphate is cleaved from the adenosine triphosphate molecule, the products are adenosine diphosphate and inorganic phosphate,  ATP + H2O  ––>  ADP  +  Pi, where Pi stands for the various forms of phosphate that exist at the pH of the particular solution.  If the total concentration of Pi  is 2.5 x 10–2M, what are the concentrations of the predominant forms of phosphate that exist at pH 7.4?     Permanganate, MnO4–, can act as an oxidizing agent in both acidic and basic aqueous solutions. Balance each of the following reactions by the half–reaction method, showing all steps in the balancing process.   MnO4–   +   Al   ––>   MnO2   +   Al(OH)4–                                in aqueous base   MnO4–   +   CH3COOH   ––>   Mn+2   +   CO2                            in aqueous acid

Assume that in a certain cell, the ratio of products/reactants or Keq = 614.9 (Keq is dimensionless) for the reaction Glucose + ATP <> Glucose-6-P + ADP, at a particular instant, the concentrations of each compound were Glucose =4.3M, ATP =10.5M, ADP =17.3M and G-6-P =23.5M. Calculate the difference (dimensionless) between Keq and the ratio of products/ractants at this instance, in this cell, to five significant figures.
