Perturbations in Generation and Flow of Energy in the Eukaryotic Cell Explain the Chromosomal Instability Syndrome
Chromosomal instability is poorly defined and used inconsistently and impre-cisely. It is the increased propensity to chromosome aberrations due to chromosome replication, repair, or segregation. Therefore, acquired genetic changes are central to leukemia development. Fast-growing cells require substantive amount of energy; however, tumor cells take up more glucose, processing it through aerobic glycolysis producing large lactate amounts with lower use of oxidative phosphorylation to gener ate ATP. The Warburg effect is characterized by reduced use of tricarboxylic acid cycle, so pyruvate made in glycolysis is converted into lactate and expelled, but this metabolic pathway is energetically inef ficient. When genes are malfunctioning, both oncogenes and tumor suppres sor genes influence negatively the switch between aerobic glycolysis and extensive use of TCA cycle to generate ATP, as the normal gene replica tion and expression require adequate energy levels. Chromosomal instability is increasingly entangled and unnecessarily complex. So far, researchers focused solely on studying the mass and have forgotten the energy. The intrinsic property of melanin to transform light into chemical energy, through water dissociation, as chloro phyll in plants, opens a new landscape in chromosome biology, highlighting the role of the environment toxics in leukemia pathogenesis, inhalation being the dominant pathway of exposure. released by dissociating the molecule of water. Molecular hydrogen easily crosses any membrane or barrier inside the cell, so the growing spheres provide energy to both the inside of the cell nucleus and the rest of the organelles located outer of the nucleus by inside cell membrane. That molecular hydrogen does not combine with water is a crucial physic-chemical of hydrogen characteristic that explains the normal displacement of molecular hydrogen (H 2 ) along cytoplasm.
