The symmetry of a carbon dioxide molecule is linear and centrosymmetric at its equilibrium geometry. The length of the carbon–oxygen bond in carbon dioxide is 116.3 pm, noticeably shorter than the roughly 140 pm length of a typical single C–O bond, and shorter than most other C–O multiply bonded functional groups such as carbonyls.

Photosynthesis changes sunlight into chemical energy, splits water to liberate O 2, and fixes CO 2 into sugar.. Most photosynthetic organisms are photoautotrophs, which means that they are able to synthesize food directly from carbon dioxide and water using energy from light.
The first experiments indicating that some plants do not use C 3 carbon fixation but instead produce malate and aspartate in the first step of carbon fixation were done in the 1950s and early 1960s by Hugo Peter Kortschak and Yuri Karpilov.
Capnography is the monitoring of the concentration or partial pressure of carbon dioxide (CO 2) in the respiratory gases.Its main development has been as a monitoring tool for use during anesthesia and intensive care.
The mixed acid fermentation pathway in E. coli. [1] [2] End products are highlighted in blue.In biochemistry, mixed acid fermentation is the metabolic process by which a six-carbon sugar (e.g. glucose, C 6 H 12 O 6) is converted into a complex and variable mixture of acids.

The oceanic carbon cycle (or marine carbon cycle) is composed of processes that exchange carbon between various pools within the ocean as well as between the atmosphere, Earth interior, and the seafloor.
The style was widely popularized when Facebook introduced Alegria, an illustration system commissioned from design agency Buck Studios and illustrator Xoana Herrera [1] in 2017. [ 4 ] The name "Corporate Memphis" originated from the title of an Are.na board that collected early examples, [ 1 ] and is a reference to the Memphis Group , a 1980s ...
