Assume that it is possible to label each of the molecules below with 18O a heavy isotope of oxygen. As a result of cellular respiration, water containing 18O would most quickly be detected if cells are provided with which one of the following molecules labeled with 18O?
a) pyruvate (C3H3O3)
b) glucose (C6H12O6)
c) carbon dioxide (CO2)
d) molecular oxygen (O2)
Why do organisms using or living in the presence of oxygen need to eliminate these chemical species ( free radicals)?
in reference to oxygen usage which organisms must produce enzymes that detoxify free radicals?
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…
