Question

What are the oxidative states of these carriers and molecules?

NAD+

      [ Choose ]            oxidized            reduced      

NADH

      [ Choose ]            oxidized            reduced      

FAD

      [ Choose ]            oxidized            reduced      

FADH2

      [ Choose ]            oxidized            reduced      

O2 (compared to water)

      [ Choose ]            oxidized            reduced      

glucose (compared to CO2)

      [ Choose ]            oxidized            reduced      

Explanation / Answer

NAD+ : oxidized (hydrogen eliminated)

NADH : reduced (hydrogen added)

FAD: oxidized (hydrogen eliminated

FADH2: reduced (hydrogen added)

O2 : oxidized (water is H2O, here H2 is eliminated)

Glucose: reduced (Glucose is C6H12O6, here oxygen and hydrogen both added but more numer of hydrogen are added in comparison to oxygen)

Note: Elimination of hydrogen and addition of oxygen is oxidation while addition of hydrogen and elimination of oxygen is reduction.
