Jan Ingenhousz FRS (8 December 1730 – 7 September 1799) was a Dutch-British [1] physiologist, biologist and chemist.. He is best known for discovering photosynthesis by showing that light is essential to the process by which green plants absorb carbon dioxide and release oxygen.
Jean Senebier (25 May 1742 [1] – 22 July 1809 [2] [3]) was a Genevan Calvinist pastor and naturalist.He was chief librarian of the Republic of Geneva. A pioneer in the field of photosynthesis research, he provided extensive evidence that plants consume carbon dioxide and produced oxygen.
The evolution of photosynthesis refers to the origin and subsequent evolution of photosynthesis, the process by which light energy is used to assemble sugars from carbon dioxide and a hydrogen and electron source such as water. It is believed that the pigments used for photosynthesis initially were used for protection from the harmful effects ...
In general outline, photosynthesis is the opposite of cellular respiration: while photosynthesis is a process of reduction of carbon dioxide to carbohydrates, cellular respiration is the oxidation of carbohydrates or other nutrients to carbon dioxide. Nutrients used in cellular respiration include carbohydrates, amino acids and fatty acids.
In the second one, the so-called "Photosynthesis Period (1951-1978)", plant micronutrient work led him to photosynthesis. [2] In 1954, Arnon, Mary Belle Allen and Frederick Robert Whatley discovered photophosphorylation in vitro. [2] In 1967, for this work, he was nominated jointly with Allen and Whatley for a Nobel Prize in Chemistry. [3]
In 1932, he commenced work on plant biochemistry, focusing on photosynthesis and the oxygen evolution of chloroplasts, leading to the discovery of the 'Hill reaction'. From 1943, Hill's work was funded by the Agricultural Research Council (ARC), although he continued to work in the Cambridge Biochemistry Department. Hill continued to receive ...
Helium is inert - it does not react with other substances or combust - and its atomic number is 2, making it the second lightest element after hydrogen. Rockets need to achieve specific speeds and ...
C 2 photosynthesis (also called glycine shuttle and photorespiratory CO 2 pump) is a CCM that works by making use of – as opposed to avoiding – photorespiration. It performs carbon refixation by delaying the breakdown of photorespired glycine, so that the molecule is shuttled from the mesophyll into the bundle sheath .
