4. What was the purpose of Miller and Urey’s experiment?
5. Explain the results of the Miller-Urey experiment. What did these finding suggest?
1.)oxygen
carbon dioxide (baking soda and vinegar)
2.)Electrodes delivered an electric current, simulating lightning, into the gas-filled chamber. After allowing the experiment to run for one week, they analyzed the contents of the liquid pool. They found that several organic amino acids had formed spontaneously from inorganic raw materials.
3.)Nonetheless, all organisms are built from the same six essential elemental ingredients: carbon, hydrogen, nitrogen, oxygen, phosphorus and sulfur (CHNOPS).
4.)The influential Miller-Urey experiment showed that with just water, ammonia, hydrogen and methane – and electric sparks to mimic lightning – you could form several of the protein precursors necessary for life on Earth. Stanley Miller and Harold Urey’s aim was to recreate the chemical conditions of early Earth.
5.)—In this brilliant experiment, Miller and Urey demonstrated that electrical sparking a mixture of methane, ammonia, and hydrogen in the presence of water produces amino acids within a variety of organic compounds. The impact of these results was so high that its mind-opening relevance hardly fades over time2.
—The classic Miller-Urey experiment demonstrated that amino acids, important building blocks of biological proteins, can be synthesized using simple starting materials under simulated prebiotic terrestrial conditions.
