  2. Isopentane - Wikipedia

    en.wikipedia.org/wiki/Isopentane

    Isopentane is a major component (sometimes 30% or more) of natural gasoline, an analog of common petroleum-derived gasoline that is condensed from natural gas. [4] Its share in commercial car fuel is highly variable: 19–45% in 1990s Sweden, [ 13 ] 4–31% in 1990s US [ 14 ] and 3.6–11% in the US in 2011. [ 15 ]

    en.wikipedia.org/wiki/Photosynthetic_efficiency

    The following is a breakdown of the energetics of the photosynthesis process from Photosynthesis by Hall and Rao: [6]. Starting with the solar spectrum falling on a leaf, 47% lost due to photons outside the 400–700 nm active range (chlorophyll uses photons between 400 and 700 nm, extracting the energy of one 700 nm photon from each one)

  5. Chemosynthesis - Wikipedia

    en.wikipedia.org/wiki/Chemosynthesis

    Venenivibrio stagnispumantis gains energy by oxidizing hydrogen gas.. In biochemistry, chemosynthesis is the biological conversion of one or more carbon-containing molecules (usually carbon dioxide or methane) and nutrients into organic matter using the oxidation of inorganic compounds (e.g., hydrogen gas, hydrogen sulfide) or ferrous ions as a source of energy, rather than sunlight, as in ...

  6. Calvin cycle - Wikipedia

    en.wikipedia.org/wiki/Calvin_cycle

    The Calvin cycle, light-independent reactions, bio synthetic phase, dark reactions, or photosynthetic carbon reduction (PCR) cycle [1] of photosynthesis is a series of chemical reactions that convert carbon dioxide and hydrogen-carrier compounds into glucose. The Calvin cycle is present in all photosynthetic eukaryotes and also many ...

    en.wikipedia.org/wiki/Photosynthesis

    Photosynthesis (/ ˌ f oʊ t ə ˈ s ɪ n θ ə s ɪ s / FOH-tə-SINTH-ə-sis) [1] is a system of biological processes by which photosynthetic organisms, such as most plants, algae, and cyanobacteria, convert light energy, typically from sunlight, into the chemical energy necessary to fuel their metabolism.

  9. Photochlorination - Wikipedia

    en.wikipedia.org/wiki/Photochlorination

    The photochlorination of hydrocarbon is unselective, although the reactivity of the C-H bonds is tertiary>secondary>primary. At 30 °C the relative reaction rates of primary, secondary and tertiary hydrogen atoms are in a relative ratio of approximately 1 to 3.25 to 4.43. The C-C bonds remain unaffected. [9] [10]
