  2. Photosynthetic efficiency - Wikipedia

    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)

  3. Penem - Wikipedia

    en.wikipedia.org/wiki/Penem

    Penem molecules do not occur naturally, and production of penems is an entirely synthetic process. Five main penem subgroups — thiopenems, oxypenems, aminopenems, alkylpenems, and arylpenems — have been produced and are distinguished by the side chain (at position 2) of the unsaturated five-membered ring.

  4. Glucose - Wikipedia

    en.wikipedia.org/wiki/Glucose

    Glucose circulates in the blood of animals as blood sugar. [6] [8] The naturally occurring form is d-glucose, while its stereoisomer l-glucose is produced synthetically in comparatively small amounts and is less biologically active. [8] Glucose is a monosaccharide containing six carbon atoms and an aldehyde group, and is therefore an aldohexose ...

  5. Carbapenem - Wikipedia

    en.wikipedia.org/wiki/Carbapenem

    Faropenem is closely related, but it is a penem, not a carbapenem. [43] Antimicrobial resistance. NDM-1 is an enzyme that introduces bacterial resistance to carbapenem antibiotics via hydrolysis of the carbapenem backbone, thereby inactivating its ability to inhibit cell wall synthesis.

  6. Photosynthetic reaction centre - Wikipedia

    en.wikipedia.org/wiki/Photosynthetic_reaction_centre

    The cooperation between Photosystems I and II creates an electron and proton flow from H 2 O to NADP +, producing NADPH needed for glucose synthesis. This pathway is called the ' Z-scheme ' because the redox diagram from H 2 O to NADP + via P680 and P700 resembles the letter Z. [ 11 ]

  7. 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 ...

  8. Photosynthesis - Wikipedia

    en.wikipedia.org/wiki/Photosynthesis

    The term photosynthesis is derived from the Greek phōs (φῶς, gleam) and sýnthesis (σύνθεσις, arranging together), [97] [98] [99] while another word that he designated was photosyntax, from sýntaxis (σύνταξις, configuration). Over time, the term photosynthesis came into common usage. Later discovery of anoxygenic ...

  9. Carbohydrate metabolism - Wikipedia

    en.wikipedia.org/wiki/Carbohydrate_metabolism

    A single glucose molecule is cleaved from a branch of glycogen, and is transformed into glucose-1-phosphate during this process. [1] This molecule can then be converted to glucose-6-phosphate, an intermediate in the glycolysis pathway. [1] Glucose-6-phosphate can then progress through glycolysis. [1]
