Question

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

Step-by-Step Solution

Answer

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

Step 1: Given information

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

Step 2: 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.
