by doing their experiment they found protein and aft sacs
I think you have Miller and Urey confused with someone else.
Oparin's hypothesis proposed that Earth's early atmosphere could have supported the formation of organic molecules, providing the foundational idea for Miller and Urey's experiment. Miller and Urey's experiment aimed to simulate early Earth conditions and demonstrated that organic molecules, including amino acids, could indeed be produced in a laboratory setting, supporting Oparin's hypothesis.
Stanley Miller and Harold Urey
The end products in Miller and Urey's experiments were various organic compounds, such as amino acids, sugars, and lipids. These molecules are building blocks of life and were synthesized in the experimental setup that simulated early Earth's conditions.
Miller and Urey observed the abiotic synthesis of amino acids, the building blocks of proteins, in their laboratory simulations of the early Earth. Additionally, they also observed the formation of other organic molecules like sugars and nucleotides, which are essential for life.
Miller and Urey's experiment demonstrated that organic compounds necessary for life, such as amino acids, could be formed from inorganic molecules under conditions similar to early Earth. This provided support for the theory that the building blocks of life could have arisen spontaneously on the primordial Earth.
The purpose of the Miller-Urey experiment was to simulate the conditions of early Earth to investigate the origins of life. They wanted to test whether organic molecules, such as amino acids, could be formed from inorganic compounds under these conditions.
Miller and Urey
The Miller-Urey experiment is not definitive proof of the origins of life. It provided important insights into how simple organic molecules could have formed on early Earth, but it does not fully explain the complex processes involved in the origin of life.
Miller and Urey created amino acids, which are important building blocks of proteins, in their experiments simulating early Earth conditions. This experiment provided evidence for the theory that the basic building blocks of life could have formed from simple molecules in the early Earth's atmosphere.
To see if biological compounds could form spontaneously on early Earth To see if simple molecules can combine spontaneously. To find out how biological molecules could have first formed How life can evolve from nonliving matter
Organic compounds will not form in the Miller-Urey apparatus if O2 is present because oxygen would react with the organic molecules produced, inhibiting the formation of more complex organic compounds. The early Earth's atmosphere was believed to be devoid of oxygen, which allowed for the formation of organic compounds in the Miller-Urey experiment.
