In 1870, he returned to the question and coined the term "abiogenesis" to contrast to " biogenesis ", the doctrine that all life arises from life.
Furthermore, cholesterol is required for macromolecular synthesis and cell growth as well as for membrane biogenesis in this microorganism.
Therefore, changes in the mitochondrial machinery of plants grown in high [CO 2] are associated with altered mitochondrial function and biogenesis and are not necessarily related to energy production.
Proteins involved with cell wall biogenesis , which display low connectivity levels, have a clear trend of later appearance.
Thomas quickly proceeds to confuse the biogenesis question with the issue of how new species arise, which he claims is "thoroughly documented."
Finally, essential processes such as transcription, translation, protein trafficking, organelle biogenesis , and secretion are likely to influence iron metabolism to different degrees and in different ways.
Needham became a strong advocate of spontaneous generation, and performed an experiment that he felt supported his belief in biogenesis .
He simultaneously established the theory of biogenesis ; the origin of life from pre-existing life.
The majority of these genes are involved in coenzyme transport and metabolism and in cellular wall and membrane biogenesis .
Replication of the mitochondrial genome is required to synthesize new protein to support biogenesis .
