As an overall result of the citric acid cycle, NADH atoms?

A. are consumed.

B. are produced,

C. act as catalysts.

D. act as oxidizing agents.

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.
