Free-energy change during electron transport

Respiration Overview

The overall energy drop (ΔG) for electrons traveling from NADH to oxygen is 53 kcal/mol, but this "fall" is broken up into a series of smaller steps by the electron transport chain. (An oxygen atom is represented here as 1/2 O2 to emphasize that the electron transport chain reduces molecular oxygen, O2 not individual oxygen atoms.)
