Answer:

As an overall result of the citric acid cycle, NADH atoms are produced.

Option: (B)

Explanation:

  • Citric acid cycle or the Tricarboxylic acid cycle is cellular metabolism of plants for the production of energy and bio-synthesis.
  • The NADH molecules are produced from the reduction of NAD+ ion in the krebs cycle/citric acid cycle.
  • NAD+ molecules can be reduced in 3 stages. During tranformation of isocitrate to α-ketoglutarato, α-ketoglutarato to succinyl CoA, malate to oxaloacetate, one NAD+ ion accepts H+ and forms NADH molecule, thus totally three NADH molecules are produced from NAD+ ions in citric acid cycle.

The correct answer is C. Act as catalysts.

(The other answer is wrong, I just took the quiz on Lesson 6: Metabolism.)
