A simplified overall formula for photosynthesis is [79] 6 CO 2 + 6 H 2 O + photons → C 6 H 12 O 6 + 6 O 2. or simply carbon dioxide + water + sunlight → glucose + dioxygen. Photolytic oxygen evolution occurs in the thylakoid membranes of photosynthetic organisms and requires the energy of four photons.
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 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.

The heating value (or energy value or calorific value) of a substance, usually a fuel or food (see food energy), is the amount of heat released during the combustion of a specified amount of it. The calorific value is the total energy released as heat when a substance undergoes complete combustion with oxygen under standard conditions .

The fire triangle or combustion triangle is a simple model for understanding the necessary ingredients for most fires. [1] The triangle illustrates the three elements a fire needs to ignite: heat, fuel, and an oxidizing agent (usually oxygen). [2] A fire naturally occurs when the elements are present and combined in the right mixture. [3]
