Question

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.

Answer 1

The correct answer is C. Act as catalysts.

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

Answer 2

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

Option: (B)

Step-by-step 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.
