Complete the reaction, which is part of the electron transport chain. The abbreviation Q represents coenzyme Q. Use the appropriate abbreviation for the product. FADH2+Q⟶ The reactant that is reduced is . In complex III, electrons are transferred from coenzyme Q to cytochrome c, which contains iron. QH2+2cyt c(Fe3+)⟶Q+2cyt c(Fex)+2H+ Determine the oxidation number for iron on the right side of the reaction arrow. x

Answer:

x = 2+

Explanation:

1) FADH2 + Q => FAD + QH2

Since H is added to Q

=> Reactant reduced is Q

(2) Balancing charges on both sides of the equation gives:

QH2 + 2 cyt c(Fe3+) => Q + 2 cyt c(Fe2+) + 2 H+

Thus x = 2+
