Oxidative Stress creates an anaerobic environment for non-normal cell growth.
Anaerobic Vs Aerobic
Anaerobic means “living in the absence of air”, as opposed to aerobic which means “living in the presence of air.” Anaerobic may also refer to a Hypoxia (environmental) (anaerobic environment), an environment with little or no available oxygen creating Anaerobic respiration, respiration in the absence of oxygen, using some other molecule as the final electron acceptor.
Aerobic processes in cellular respiration can only occur if oxygen is present. When a cell needs to release energy, the cytoplasm (a substance between a cell’s nucleus and its membrane) and mitochondria (organelles in the cytoplasm that help with metabolic processes) initiate chemical exchanges that launch the breakdown of glucose. This sugar is carried through the blood and stored in the body as a fast source of energy.
The existence of common features in different forms of life indicates some relationship between the different organisms, and according to the concept of evolution these relations stem from the circumstance that the higher organisms, in the course of millions of years, have gradually evolved from simpler ones. The concept of evolution postulates that living organisms have common roots, and in turn, the existence of common features is powerful support for the concept of evolution. The presence of the same mechanism of energy production in all forms of life suggests two other inferences, firstly, that the mechanism of energy production has arisen very early in the evolutionary process, and secondly, that life, in its present forms, has arisen only once.
