Question

What is the total $\mathrm{NADH}$ and total ${\mathrm{FADH}}_2$ produced in one turn of the citric acid cycle?

Short answer

The three$\mathrm{NADH}$and one${\mathrm{FADH}}_2$produced in one turn of the citric acid cycle

Step-by-step solution

Given information

We need to find the$\mathrm{NADH}$and${\mathrm{FADH}}_2$produced in one turn of the citric acid cycle

Explanation

We know that

Three ${\mathrm{NAD}}^{+}$are reduced to three $\mathrm{NADH}$in one rotation of the citric acid cycle via four oxidation processes. They also convert one $\mathrm{FAD}$to one ${\mathrm{FADH}}_2$. For one rotation of the citric acid cycle, the overall chemical equation is:

localid="1653780193482" role="math" $$\begin{gathered} \mathrm{Acetyl}-\mathrm{CoA}+3{\mathrm{NAD}}^{+}+\mathrm{FAD}+\mathrm{GDP}+{\mathrm{P}}_{\mathrm{i}}+2{\mathrm{H}}_2\mathrm{O}\to \\ 2{\mathrm{CO}}_2+3\mathrm{NADH}+3{\mathrm{H}}^{+}+{\mathrm{FADH}}_2+\mathrm{HS}-\mathrm{CoA}+\mathrm{GTP} \end{gathered}$$
