As an overall result of the citric acid cycle, nadh atoms are consumed. are produced. act as catalysts. act as oxidizing agents.

Are produced.

NADH molecules are produced during the citric acid cycle, or Krebs cycle, from the reduction of the NAD+ molecules. NAD+ molecules can be reduced in three different stages of the cycle. From isocitrate to α-ketoglutarato, one NAD+ receives an H+ and it becomes NADH. The same process happens again with other NAD+ molecules when from α-ketoglutarato to succinyl CoA, and when from malate to oxaloacetate.
