Question

Which reaction(s) of the citric acid cycle involve(s) the production of a carbon-carbon double bond?

Short answer

The reaction$6$ of the citric acid cycle involve(s) the production of a carbon-carbon double bond

Step-by-step solution

Given information

We need to find the reaction(s) of the citric acid cycle involve(s) the production of a carbon-carbon double bond

Explanation

As we can see in Reaction $6$, dehydrogenation of succinate removes two hydrogen ions from the parent chain, resulting in the production of a carbon-carbon double bond. As demonstrated below, these hydrogen ions convert data-custom-editor="chemistry" $\mathrm{FAD}$to data-custom-editor="chemistry" ${\mathrm{FADH}}_2$.

As a result, Reaction $6$is the reaction that has resulted in the formation of a carbon-carbon double bond.
