Last 2 people got this wrong, posting a third time... Thanks
You to try to create your own artificial electron chain using the molecules C, D, F, G, and H. The redox potentials of these molecules, along with those for NADH and water, are given below. Order the molecules from 1 to 5, in the order they would be used in an electron transport chain, from those that has the lowest affinity for electron (= # 1) to those with the greatest affinity for electrons (= #5). Would the electron transport chain you create using molecules C, D, F, G, and H be able to donate an electron to molecular oxygen to create water (like what happens in the mitochondria)? Explain your answer.Explanation / Answer
The redox potential is a measure (in volts) of the affinity of a substance for electrons i.e its electronegativity as compared with hydrogen (which is set at 0).
Substances more strongly electronegative than (i.e., capable of oxidising) hydrogen have positive redox potentials. Substances less electronegative than (i.e., capable ofreducing) hydrogen have negativeredox potentials (Biologypages).
i) Order from lowest electron affinity to highest is:
a) F b) G c) C d) H e) D
ii) Since the redox potential required for the reaction to donatae electrons to molecular oxygen to create water is = +820 and since the redox potential of D is +925 this reaction is possible in this electron transport chain arranged in this fashion : F b) G c) C d) H e) D with electrons being finally transferred from D to molecular Oxygen as it is energetically possible
