He also studied the biochemistry of material processing by plants and enzyme reactions in plant cells. He showed that many food-production processes were based on biocatalysis and developed the foundations for industrial biochemistry in the USSR. Born in Uglich in , Oparin graduated from the Moscow State University in and became a professor of biochemistry there in Many of his early papers were about plant enzymes and their role in metabolism.

In s and s he supported the theories of Trofim Lysenko and Olga Lepeshinskaya , who made claims about "the origin of cells from noncellular matter". Oparin became Hero of Socialist Labour in , received the Lenin Prize in and was awarded the Lomonosov Gold Medal in "for outstanding achievements in biochemistry".

He was also a five-time recipient of the Order of Lenin. Although Oparin's started out reviewing various panspermia theories, including those of Hermann von Helmholtz and William Thomson Kelvin , [3] he was primarily interested in how life began. As early as , he asserted that:. Oparin outlined a way he thought that basic organic chemicals might have formed into microscopic localized systems, from which primitive living things could have developed.

He cited work done by de Jong and Sidney W. Fox on coacervates and research by others, including himself, into organic chemicals which, in solution, might spontaneously form droplets and layers. Oparin suggested that different types of coacervates could have formed in the Earth's primordial ocean and been subject to a selection process that led, eventually, to life. While Oparin himself was unable to conduct experiments to test any of these ideas, later researchers tried.

In , Stanley Miller attempted an experiment to investigate whether chemical self-organization could have been possible on pre-historic Earth. The Miller—Urey experiment introduced heat to provide reflux and electrical energy sparks, to simulate lightning into a mixture of several simple components that would be present in a reducing atmosphere. Within a fairly short period of time a variety of familiar organic compounds, such as amino acids , were synthesised.

The compounds that formed were somewhat more complex than the molecules present at the beginning of the experiment. The Communist Party 's official interpretation of Marxism , dialectical materialism , fit Oparin's speculation on the origins of life as 'a flow, an exchange, a dialectical unity'. This notion was re-enforced by Oparin's association with Lysenko. From Wikipedia, the free encyclopedia. Alexander Oparin. Uglich , Russian Empire [1].

Antonio Lazcano

Lazcano pursued his undergraduate and graduate studies at UNAM, where he focused on the study of prebiotic evolution and the emergence of life. A great honor, for Alexander Oparin , Stanley L. Miller and J. Lazcano has devoted considerable efforts to promote scientific journalism and teaching. He also promotes the study of evolutionary biology and the origins of life, all over the world.
