Proteins are famous for their ability to catalyze biochemical reactions. However,

proteins have other functions in microorganisms. Name at least six other

functions and indicate if the function is common among most microorganisms

or specific to select microbial types.

The standard potentials (at pH = 7) are given for some important donors and

acceptors:

Reduced Species, Oxidized Product, Potential( V)

H2, H -041

H2O, 02, +0.822

H2 S, so4, -0.22

N2, No3, +0.75

Fe2+, Fe3+, +0.77

CH4 ,CO2, -0.24

Compute the overall standard potential (at pH 7) for transfer of electrons from

the follow pairs ofdonors and acceptors. Rank them from most energetic (most

positive) to least energetic: H2/Fe3+, H2S/02, CH4IN03", H2/02, Fe2+102,

and H2SIN03"
