Question

Complete the reaction, which is part of the electron transport chain. The abbreviation FMN represents flavin mononucleotide. Use the appropriate abbreviation for the product. NADH + H + + FMN ⟶ NAD +FMNH_{2} NAD + FMNH 2 The reactant that is reduced is FMN . In complex III, electrons are transferred from coenzyme Q to cytochrome c, which contains iron. QH 2 + 2 cyt c ( Fe 3 + ) ⟶ Q + 2 cyt c ( Fe x ) + 2 H + Determine the oxidation number for iron on the right side of the reaction arrow.

Answer 1

Answer:

Oxidation number of Fe(iron) on right side of reaction arrow = (+2)

Explanation:

NADH+H+ + FMN   FMNH2 + NAD+

FMNH2 - Reduced FMN (1,5-Dihydroriboflavin 5'-(dihydrogen phosphate)

The reactant that is reduced is Flavin mononucleotide(FMN)

QH2 + 2cyt c(fe³+)  ----------------------->  Q + 2Cytc ( fe²+) + 2H+

Oxidation number of Fe(iron) on right side of reaction arrow = (+2)
