Scientist Otto Warburg, whose research activities led to the formulation of the Warburg hypothesis for explaining the root cause of cancer.. The Warburg hypothesis (/ ˈ v ɑːr b ʊər ɡ /), sometimes known as the Warburg theory of cancer, postulates that the driver of carcinogenesis (cancer formation) is insufficient cellular respiration caused by insult (damage) to mitochondria.

A gas evolution reaction is a chemical reaction in which one of the end products is a gas such as oxygen or carbon dioxide. [ 1 ] [ 2 ] Gas evolution reactions may be carried out in a fume chamber when the gases produced are poisonous when inhaled or explosive.
In cancer cells, major changes in gene expression increase glucose uptake to support their rapid growth. Unlike normal cells, which produce lactate only when oxygen is low, cancer cells convert much of the glucose to lactate even in the presence of adequate oxygen. This is known as the “Warburg Effect.”
The international pictogram for oxidizing chemicals. Dangerous goods label for oxidizing agents. An oxidizing agent (also known as an oxidant, oxidizer, electron recipient, or electron acceptor) is a substance in a redox chemical reaction that gains or "accepts"/"receives" an electron from a reducing agent (called the reductant, reducer, or electron donor).
Metals react with acids to form salts and hydrogen gas. Liberation of hydrogen gas when zinc reacts with hydrochloric acid. + () + [2] [3] However less reactive metals can not displace the hydrogen from acids. [3] (They may react with oxidizing acids though.) + No reaction
Some polymerization reactions such as the setting of epoxy resin; The reaction of most metals with halogens or oxygen; Nuclear fusion in hydrogen bombs and in stellar cores (to iron) Nuclear fission of heavy elements; The reaction between zinc and hydrochloric acid; Respiration (breaking down of glucose to release energy in cells)
Zinc oxide is an inorganic compound with the formula Zn O.It is a white powder which is insoluble in water. ZnO is used as an additive in numerous materials and products including cosmetics, food supplements, rubbers, plastics, ceramics, glass, cement, lubricants, [12] paints, sunscreens, ointments, adhesives, sealants, pigments, foods, batteries, ferrites, fire retardants, semi conductors ...
Rust is an iron oxide, a usually reddish-brown oxide formed by the reaction of iron and oxygen in the catalytic presence of water or air moisture.Rust consists of hydrous iron(III) oxides (Fe 2 O 3 ·nH 2 O) and iron(III) oxide-hydroxide (FeO(OH), Fe(OH) 3), and is typically associated with the corrosion of refined iron.
