Otto Heinrich Warburg (German pronunciation: [ˈɔto ˈvaːɐ̯bʊʁk] ⓘ, / ˈ v ɑːr b ɜːr ɡ /; 8 October 1883 – 1 August 1970) was a German physiologist, medical doctor, and Nobel laureate. He served as an officer in the elite Uhlan (cavalry regiment) during the First World War, and was awarded the Iron Cross (1st Class) for bravery ...
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. [1]
In plant physiology, the Warburg effect is the decrease in the rate of photosynthesis due to high oxygen concentrations. [1] [2] Oxygen is a competitive inhibitor of carbon dioxide fixation by RuBisCO which initiates photosynthesis. Furthermore, oxygen stimulates photorespiration which reduces photosynthetic output. These two mechanisms working ...
Emerson received a master's degree in 1929 from Harvard, and received his doctorate from the University of Berlin working in the laboratory of Otto Warburg. [3] [1]Thomas Hunt Morgan invited him to join the Biology Division at the California Institute of Technology where he worked from 1930 to 1937, and again for a year in 1941 and 1945.
Otto Warburg postulated this change in metabolism is the fundamental cause of cancer, [8] a claim now known as the Warburg hypothesis. Today, mutations in oncogenes and tumor suppressor genes are thought to be responsible for malignant transformation, and the Warburg effect is considered to be a result of these mutations rather than a cause. [9 ...
Otto Heinrich Warburg and Dean Burk discovered the I-quantum photosynthesis reaction that splits CO 2, activated by the respiration. [92] In 1950, first experimental evidence for the existence of photophosphorylation in vivo was presented by Otto Kandler using intact Chlorella cells and interpreting his findings as light-dependent ATP formation ...
Dean Burk and Otto Heinrich Warburg discovered the photosynthesis I-quantum reaction that splits CO 2 activated by respiration. [ 16 ] [ 17 ] For his techniques to distinguish between normal cells and those damaged by cancer, Dean Burk was awarded the Gerhard Domagk Prize in 1965.
German biochemist and cell physiologist Otto Heinrich Warburg, awarded with the Nobel Prize in Physiology or Medicine in 1931 for his research on cell respiration, also studied photosynthesis in Chlorella.
