Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which of these reactions in the TCA cycle produce FADH2
A
succinyl CoA ____
B
succinate ____
C
isocitrate ____
D
Explanation: 

Detailed explanation-1: -In the 6th step of Krebs cycle, oxidation of succinate occurs. Succinate undergoes dehydrogenation to form fumarate with the help of a membrane based enzyme succinate dehydrogenase. FADH2 (reduced flavin adenine dinucleotide) is produced in this step.

Detailed explanation-2: -One kreb’s cycle gives 2FADH2 molecules, it takes 3 cycles to produce 6FADH2.

Detailed explanation-3: -7: The Citric Acid Cycle, Step 6. Succinate is oxidized to fumarate. During this oxidation, FAD is reduced to FADH2.

Detailed explanation-4: -These products from the citric acid cycle are made in the mitochondria of your cells.. During oxidative phosphorylation, NADH and FADH 2start subscript, 2, end subscript are transported to the electron transport chain, where their high energy electrons will ultimately drive synthesis of ATP.
