  2. Nicotinamide adenine dinucleotide - Wikipedia

    en.wikipedia.org/wiki/Nicotinamide_adenine_di...

    In cellular metabolism, NAD is involved in redox reactions, carrying electrons from one reaction to another, so it is found in two forms: NAD + is an oxidizing agent, accepting electrons from other molecules and becoming reduced; with H +, this reaction forms NADH, which can be used as a reducing agent to donate electrons.

    The electrons are then transferred through the FMN via a series of iron-sulfur (Fe-S) clusters, [10] and finally to coenzyme Q10 (ubiquinone). This electron flow changes the redox state of the protein, inducing conformational changes of the protein which alters the p K values of ionizable side chain, and causes four hydrogen ions to be pumped ...

  4. Hydrogen dehydrogenase (NADP+) - Wikipedia

    en.wikipedia.org/wiki/Hydrogen_dehydrogenase_(NADP+)

    In enzymology, a hydrogen dehydrogenase (NADP+) (EC 1.12.1.3) is an enzyme that catalyzes the chemical reaction. H 2 + NADP + H + + NADPH. Thus, the two substrates of this enzyme are H 2 and NADP +, whereas its two products are H + and NADPH.

  5. Light-dependent reactions - Wikipedia

    en.wikipedia.org/wiki/Light-dependent_reactions

    "P" here means pigment, and the number following it is the wavelength of light absorbed. Electrons in pigment molecules can exist at specific energy levels. Under normal circumstances, they are at the lowest possible energy level, the ground state. However, absorption of light of the right photon energy can lift them to a higher energy level.

    Because NAD+ is essential to every single cell in our body, its fans link the molecule to a hyperbolic list of benefits: It gives you tons of energy during the day and helps you sleep better at ...

  7. Anaerobic respiration - Wikipedia

    en.wikipedia.org/wiki/Anaerobic_respiration

    Anaerobic cellular respiration and fermentation generate ATP in very different ways, and the terms should not be treated as synonyms. Cellular respiration (both aerobic and anaerobic) uses highly reduced chemical compounds such as NADH and FADH 2 (for example produced during glycolysis and the citric acid cycle) to establish an electrochemical gradient (often a proton gradient) across a membrane.

  8. Thermionic emission - Wikipedia

    en.wikipedia.org/wiki/Thermionic_emission

    In fact, by about 1930 there was agreement that, due to the wave-like nature of electrons, some proportion r av of the outgoing electrons would be reflected as they reached the emitter surface, so the emission current density would be reduced, and λ R would have the value 1 − r av. Thus, one sometimes sees the thermionic emission equation ...

  9. Lactate dehydrogenase - Wikipedia

    en.wikipedia.org/wiki/Lactate_dehydrogenase

    Reaction catalyzed by lactate dehydrogenase. Lactate dehydrogenase catalyzes the interconversion of pyruvate and lactate with concomitant interconversion of NADH and NAD +.It converts pyruvate, the final product of glycolysis, to lactate when oxygen is absent or in short supply, and it performs the reverse reaction during the Cori cycle in the liver.
