In nature, many electron transfer reactions take place which are catalyzed by enzymes. Two such half-cell reactions are gathered 2 H ⁺( aq )+2 e H ₂( ~g , 1 ~atm ) O ₂( ~g , 1 ~atm )+4 H ⁺( aq )+4 e 2 H ₂ O ( l ) E₀=1.23 ~V gathered The reduction potentials for the two half-cell reactions respectively at the physiological pH 7 are:
