Energy Span of the Respiratory Chain

Energy Span of the Respiratory Chain: Electron transfer in the mitochondrial respiratory chain may be represented by the net reaction equation:

NADH + H+ + ½ O2 H2O + NAD+

(a) Calculate the value of ?E'0 for the net reaction of mitochondrial electron transfer. Use E'0 values from table below.

(b) Calculate ?G'0 for this reaction.

(c) How many ATP molecules can theoretically be generated by this reaction if the free energy of ATP synthesis under cellular conditions is 52kj/mol?
