  2. Glycerol-3-phosphate dehydrogenase - Wikipedia

    The NAD+/NADH coenzyme couple act as an electron reservoir for metabolic redox reactions, carrying electrons from one reaction to another. [5] Most of these metabolism reactions occur in the mitochondria. To regenerate NAD+ for further use, NADH pools in the cytosol must be reoxidized.

  3. 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 ...

    A new study explains how mitochondria act as “reservoirs” to store NAD for cells to use, which could help scientists come up with NAD-boosting therapies to combat aging and age-related diseases.

  6. 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.

    Peer-reviewed human studies are lacking; however, in a number of independent clinical studies over the past 10 years, NAD+ did show positive health impacts, like slowing the progression of ...

  8. NAD+ kinase - Wikipedia

    en.wikipedia.org/wiki/NAD+_kinase

    NAD + kinase (EC 2.7.1.23, NADK) is an enzyme that converts nicotinamide adenine dinucleotide (NAD +) into NADP + through phosphorylating the NAD + coenzyme. [6] NADP + is an essential coenzyme that is reduced to NADPH primarily by the pentose phosphate pathway to provide reducing power in biosynthetic processes such as fatty acid biosynthesis and nucleotide synthesis. [7]

  9. Ferredoxin—NADP(+) reductase - Wikipedia

    en.wikipedia.org/wiki/Ferredoxin—NADP(+)_reductase

    Ferredoxin: NADP + reductase is the last enzyme in the transfer of electrons during photosynthesis from photosystem I to NADPH. [2] The NADPH is then used as a reducing equivalent in the reactions of the Calvin cycle. [2] Electron cycling from ferredoxin to NADPH only occurs in the light in part because FNR activity is inhibited in the dark. [11]
