The reactants for fermentation are:
1.) Pyruvate
2.) NADH
3.) A proton
The products are a lactate and NAD+.
The process of fermentation results in the reduction of pyruvate to form lactate acid and the oxidation of NADH to form NAD+
The most inclusive division of time is the eon, which can be Archean, Proterozoic, Phanerozoic and they are divided into eras (Early/Middle/Late for the Archean and Proterozoic, Paleozoic, Mesozoic and Cenozoic for the Phanerozoic). Therefore, the correct answer is D. eon.
