According to most theories about the evolution of early life on earth, the atmosphere had an abundance of ammonia, methane, and carbon dioxide, shown above. free energy from lightning could have allowed chemical reactions to occur that generated the precursors to life on earth. which inorganic molecule(s) are accurately paired with their role in the formation of organic molecules necessary to life?
a) ammonia would have provided the nitrogen found in the amine groups of amino acid and the nitrogenous bases in dna.
b) methane would have provided the hydrogen to form water, a universal solvent for chemical reactions supporting life.
c) ammonia would have provided the electrons to generate atp using an electron transport chain within the mitochondria.
d) carbon dioxide would have provided the oxygen needed to perform photosynthesis, resulting in the production of glucose.
