Web13 de mai. de 2024 · Oparin suggested that abundant sources of free energy fueled the reductive synthesis of the first organic molecules to create what he called a “primeval soup”. No doubt, he called this primeval concoction a “soup” because it would have been rich in chemical (nutrient) free energy. Web13 de mai. de 2024 · Oparin and Haldane hypothesized a reducing atmosphere on the prebiotic earth, rich in inorganic molecules with reducing power (like H 2, NH 3, CH 4, and H 2 S) as well as CO 2 to serve as a carbon source. The predicted physical conditions on this prebiotic earth were: lots of water (oceans). hot (no free O 2 ).
