Concept explainers
To determine: The additional components needed for the formation of amino acids and other precursors of macromolecules important for life from gases.
Introduction: The reactions that occurred in the primitive earth’s atmosphere to form the amino acids or other monomers of macromolecules were endergonic. Endergonic suggests need or absorption of energy to carry out the reaction. Thus, the whole idea suggests that subsequent chemical evolution led to the formation of life.
To explain : Whether these components have been available on primitive earth.
Introduction: The primitive atmosphere of the earth was in abundance of hydrogen. All the other components were present in their reducing forms. Thus, this could be concluded that the early precursors of life would have evolved from inorganic molecules.
