FAD - flavin adenine dinucleotide. This is the physiologically functional form of ribofavin (Vitamin B2). FAD is synthesized from riboflavin and ATP. The normal daily requirement for riboflavin is 1.2 - 1.7 mg/day for normal adults.

NAD - nicotinamide adenine dinucleotide. This is the physiologically functional form of nicotinamide (Vitamin B3). The recommended daily requirement for niacin is 13 - 19 niacin equivalents (NE) per day for a normal adult. One NE is equivalent to 1 mg of free niacin.

The key feature here is that the vitamin - that is, the trace ...

  • ATP by substrate level phosphorylation

    One important difference is that they do not use NAD/NADH. At every step in the oxidation of biological molecules where humans use NAD/NADH aliens use FAD/FADH-2. At steps where humans use FAD/FADH-2 the aliens do as well. a.

  • Oxidation of Succinate and Malate

    Oxidative phosphorylation in the mitochondria involves the production of ATPs with the oxidation of electron energy carriers: 1. FAD and 2.

  • Cellular respiration

    Most ATP is generated during the electron tranport chain (oxidative phosphorylation) when the hydrogens attached to NAD and FAD (attached during glycolyis, the link reaction and Krebs cycle) are removed and transferred to other carriers at progressively

  • Aerobic respiration is the oxygen actually used

    In the process, NAD+ and FAD are formed. ATP is produced in the process. Of course, the NAD+ and FAD can go back to glycolysis and the Krebs cycle and be used over again to help in the oxidation of sugars.

  • Electron Transport Chain.

    cytochrome a coenzyme Q FAD cytochrome c NAD+ Rank the following redox-active coenzymes and prosthetic groups of the electron-transport chain in order of increasing electron affinity.

  • Discussion of metabolism questions

    Why is FAD being used here instead of NAD?

  • Cyanide's Effects on the Electron Transport System

    This means that NAD+ and FAD are not generated and therefore cannot be used by the TCA cycle to oxidize pyruvate to CO2.

  • Questions Based on the Action of Pyruvate

    Low levels of molecular oxygen cause a reduction in oxidative phosphorylation. Therefore, the reduced co-factors, NADH and FADH2, cannot be re-oxidized back to their oxidized form, NAD+ and FAD. Therefore, NADH accumulates in the cell.

  • Fermentation after glycolis

    When glucose is oxidized to pyruvate (glycolysis), and then all the way to carbon dioxide in the Krebs cycle, an enormous amount of free energy is given off. Most of this free energy is captured by reduced cofactors, NADH and FADH2.
