  1. CH2O refers to an idealized reduced organic carbon (including pyruvate, acetate, formate, fumurate, methanol, etc.)
  2. hv electromagnetic radiation
  3. aEquations are unbalanced, and some of the chemoautotrophic pathways do not illustrate carbon reduction, as many of these organisms are mixotrophs, employing both autotrophic and heterotrophic mechanisms based on context
