ADP + Pi <-----> ATP ΔG = + 7 kcal/mole How long will this reaction take to reach equilibrium at 37˚ C and pH = 7. (There may be more than one correct answer.) Can't predict. Can't predict exactly but it will be fast. Can't predict exactly but it will be slow. Can't tell but it would be faster at 100˚C. Can't tell but it would be slower at 100˚C.

The transport of Na+ ions across a membrane, from a region where the concentration is 1 μM to a region where it is 100 μM, is coupled to the hydrolysis of ATP. Transport is opposed by a membrane potential of 70 mV. Assuming energy coupling is 100% efficient, the hydrolysis of 1 mole of ATP can drive the transport of how many moles of Na+ at 37˚C if the ΔG for ATP hydrolysis is -53.4 kJ/mol under intracellular conditions?

Some bacteria can use nitrate as an electron acceptor instead of oxygen, reducing it to nitrite. This requires an enzyme called nitrate reductase. The reduction and oxidation redox equations I am using are: NO3- +2H+ +2e- ---> NO2- + H2O NAD+ + 2H+ +2e- ---> NADH + H+ I calculated the Gibbs free energy change under standard state conditions for the oxidation of NADH by nitrate to be -144.75 kJ/mol. Please use the value to help solve part a. Please...
