Answer 1

Answer #1

When the NADH molecule and QH are oxidized in to NAD+ and Q back, the reducing power is carried to O2 to reduce O2 to H2O. During this process there is H+ ion gradient generated. Which while diffusing releases proton motive force to form ATP.

The right option---a =O2 to H2O, b=ATP

10. A number of molecules can act as electron carriers in biological systems. In cellular respiration, there are two important electron carriers, one of them being nicotinamide adenine dinucleotide. The NADH moves to the electron transport chain and donates a pair of electrons and protons resulting in NAD+. This oxidation process of NADH to NAD+ results in the liberation of 53 kcal/mole (under standard conditions), a. Considering the following reaction scheme, where does this energy come from? b. Which molecule...

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...
