The difference between an oxidation reaction and a reduction reaction is that oxidation is the _____ correct answers loss of electrons and reduction is the gain of electrons. If the Gibbs free energy change value for a reaction is less than zero, this reaction is ______ correct answers exergonic Flux is defined as the rate at which ___ is/are interconverted. correct answers Metabolites Enzyme active sites... correct answers Are characterized as a pocket or cleft Which answer correctl...

Protons are pumped by mitochondria during active electron transport correct answers outside the inner mitochondrial membrane. As electrons from NADH pass through the electron transport system, correct answers protons are pumped across the mitochondrial membrane to create a pH gradient. The first enzyme in the electron transport system is referred to as complex I, otherwise known as correct answers NADH-ubiquinone oxidoreductase. Which statement is true of the mitochondrial electron tran...
