Mitochondrial biogenesis is the process by which cells increase mitochondrial numbers. [ 1 ] [ 2 ] It was first described by John Holloszy in the 1960s, when it was discovered that physical endurance training induced higher mitochondrial content levels, leading to greater glucose uptake by muscles. [ 3 ]
NASA's 2015 strategy for astrobiology aimed to solve the puzzle of the origin of life – how a fully functioning living system could emerge from non-living components – through research on the prebiotic origin of life's chemicals, both in space and on planets, as well as the functioning of early biomolecules to catalyse reactions and support inheritance.
Organelle biogenesis is the biogenesis, or creation, of cellular organelles in cells. Organelle biogenesis includes the process by which cellular organelles are split between daughter cells during mitosis ; this process is called organelle inheritance.
Pasteur and others used the term biogenesis as the opposite of spontaneous generation, to mean that life was generated only from other life. Pasteur's claim followed the German physician Rudolf Virchow 's doctrine Omnis cellula e cellula ("all cells from cells"), [ 49 ] itself derived from the work of Robert Remak .
Konstantin Mereschkowski's 1905 tree-of-life diagram, showing the origin of complex life-forms by two episodes of symbiogenesis, the incorporation of symbiotic bacteria to form successively nuclei and chloroplasts [4]
Ribosome biogenesis is a very tightly regulated process, and it is closely linked to other cellular activities like growth and division. [3] [4] Some have speculated that in the origin of life, ribosome biogenesis predates cells, and that genes and cells evolved to enhance the reproductive capacity of ribosomes. [5]
Biogenesis is the generation of life from existing life. Biogenesis may also refer to: "Biogenesis" (The X-Files) Biogenesis baseball scandal (involving MLB players taking growth-hormone) Mitochondrial biogenesis; Organelle biogenesis; Ribosome biogenesis; Recapitulation theory, the biogenetic law of Ernst Haeckel
Antonie van Leeuwenhoek. Traditional religion attributed the origin of life to deities who created the natural world. Spontaneous generation, the first naturalistic theory of abiogenesis, goes back to Aristotle and ancient Greek philosophy, and continued to have support in Western scholarship until the 19th century.
