  • What is the role of NAD+ and NADH in the cell?

  • At various chemical reactions, the NAD+ picks up an electron from glucose, at which point it becomes NADH. Then NADH, along with another molecule flavin adenine dinucleotide (FADH2) will ultimately transport the electrons to the mitochondria, where the cell can harvest energy stored in the electrons.

  • What is the role of NADH and FADH2 in ATP production?

  • ATP production is an important part of cellular respiration (the process of generating energy from food) and both NADH and FADH2 that are involved in this process help in making more ATP. It is observed that during cellular respiration, every NADH molecule produces 3 ATP molecules, whereas each FADH2 molecule generates 2 ATP molecules.

  • How many electrons does NADH and FADH2 carry?

  • Basically, the NADH and FADH2 molecules are affixed with electrons and are transferred to the inner membrane of the mitochondria. They travel down the electron transport chain, releasing the electrons that they once had. The end result is loads of energy, approximately 34 ATP (energy molecule). How many electrons does fad carry? two electrons

  • How is ATP made from NADH?

  • All of these ATP are created using the electron carrying powers of NADH and FADH2. At the end, since they’ve given away their electrons, NADH and FADH2 are converted to their oxidized forms, NAD+ and FAD+. Now, they are ready to go back to the starting point and be used again.
