  • Methanogenesis: Current Biology

    Methanogenesis is an anaerobic respiration that generates methane as the final product of metabolism. In aerobic respiration, organic matter such as glucose is oxidized to CO 2, and O 2 is reduced to H 2 O. In contrast, during hydrogenotrophic methanogenesis, H 2 is oxidized to H +, and CO 2 is reduced to CH 4.Although similar in principle to other types of respiration, methanogenesis has some ...
