(b) alpha-ketoglutarate to succinyl CoA
(c) succinic acid to fumaric acid
(d) furmaric acid to malic acid
Correct Answer:
succinic acid to fumaric acid
Explanation:
Krebs cycle occurs in matric of mitochondria. In one of the steps in Krebs cycle or TCA cycle, succinic acid is oxidised to fumaric acid by the help of enzyme succinic acid dehydrogenase. In this step FAD takes up two hydrogen ions and the two electrons from succinic acid and get reduced.
Succinic acid + FAD ⇌ Fumaric acid + FADH₂.
