U nucleus has an excitation energy below the critical fission energy." [4]: 25–28 [5]: 282–287 [10] [11] About 6 MeV of the fission-input energy is supplied by the simple binding of an extra neutron to the heavy nucleus via the strong force; however, in many fissionable isotopes, this amount of energy is not enough for fission.
Binary fission is generally rapid, though its speed varies between species. For E. coli, cells typically divide about every 20 minutes at 37 °C. [11] Because the new cells will, in turn, undergo binary fission on their own, the time binary fission requires is also the time the bacterial culture requires to double in the number of cells it ...
The web page traces the history of nuclear fission from the discovery of radioactivity by Becquerel and the Curies to the Nobel Prize-winning work of Hahn, Meitner, Strassmann and Frisch in 1938. It also explains the mechanism, applications and background of fission, and the role of neutrons, isotopes and elements in the process.
Cellular respiration is the process of converting nutrients into energy (ATP) and waste products in the cells of living organisms. It can be aerobic (using oxygen) or anaerobic (using other electron acceptors), and involves glycolysis, Krebs cycle, and electron transport chain.
Learn about the different types of cellular respiration and their waste products, such as aerobic respiration, anaerobic respiration, and fermentation. The primary waste product of aerobic respiration is carbon dioxide, which is produced in the presence of oxygen.
The significance of mitochondrial fission and fusion is distinct for nonproliferating neurons, which are unable to survive without mitochondrial fission. Such nonproliferating neurons cause two human diseases known as dominant optic atrophy and Charcot Marie Tooth disease type 2A, which are both caused by fusion defects. Though the importance ...
Cell division is the process by which a parent cell divides into two daughter cells, either genetically identical (mitosis) or with reduced chromosomes (meiosis). Learn about the different forms of cell division in prokaryotes and eukaryotes, and the stages of the cell cycle and DNA replication.
Mitochondrial network (green) in two human cells ()Mitochondrial fission is the process where mitochondria divide or segregate into two separate mitochondrial organelles. . Mitochondrial fission is counteracted by the process of mitochondrial fusion, whereby two separate mitochondria can fuse together to form a large one.
