The Miller- Urey Experiment In the Stanley Miller and Harald Urey designed experiments that tested Alexander Oparin's and J.B.S. Haldane's hypothesis that conditions on the primitive Earth favored chemical reactions that synthesized more complex organic compounds from simpler organic precursors. Miller and Urey used an apparatus that recreated the conditions of what a primitive Earth was thought to consist of at the time. Methane, hydrogen , and steam were all Included to recreate conditions similar to that of a primitive Earth. Their goal was to create complex organic molecules from the simple organic molecules that were believed to be part of primitive Earth's makeup. The Miller- Urey experiment was run for a week and the samples collected were analyzedAnalysis showed that some of the carbon in the apparatus was converted to amino acids molecules, In later experiments , similar to Miller and Urey's, it has been shown that it is possible to form all 20 amino acids commonly found in…
Animals obtain energy through a series of chemical reactions in which sugar (C6H12O6) and oxygen gas (O2) are reactants. This process produces water (H2O) and carbon dioxide (CO2 ) as waste products. How might you use a radioactive isotope to find out whether the oxygen in CO2 comes from sugar or from oxygen gas?
