Hydrogen-Generating Reactions in Syntrophus and Syntrophomonas Have $\Delta$ G°' > 0 Can These Organisms Obtain Energy from Hydrogen Formation?
A)

Hydrogen-generating reactions in Syntrophus and Syntrophomonas have $\Delta$ G°' > 0. Can these organisms obtain energy from hydrogen formation?

A) No, they cannot.
B) No. They produce energy by breaking down molecules such as benzoate or butyrate.
C) Yes. Hydrogen-producing microorganisms coexist in syntrophy with H₂-consuming bacteria. Utilization of H₂ ( $\Delta$ G°' < 0) drives the process forward.
D) All of the above.
E) None of the above.
