TERMS TO KNOW
  • NAD+ and NADH

    NAD+  is a molecule that picks up hydrogen atoms and becomes NADH which is then transferred to the electron transport chain to produce more ATP from the energy in electrons.

  • FADH2 and FAD

    FAD is a molecule that picks up hydrogen atoms and becomes FADH2 which is then transferred to the electron transport chain to produce more ATP from the energy in electrons.

  • Acetyl CoA

    A molecule produced from pyruvate which enters the Krebs cycle to produce ATP.

  • Coenzyme A


    An enzyme used to change pyruvate into acetyl CoA which enters the Krebs cycle.

  • ​Krebs Cycle

    The second stage of cellular respiration in which pyruvate from glucose is used to produce ATP, NADH and FADH2.
