This question has multiple parts. Work all the parts to get the most points. There is a reaction in which succinate reacts with FAD to give fumarate and FADH2 FADH, OOC FAD COO Succinate FumarateExplanation / Answer
1) Answer : A ( Succinate )
Oxidation : It is the process in which loss of electrons or loss of hydrogen or gain of oxygen occurs
In this reaction Succinate is losing two hydrogen to become fumarate.
The compound which loses hydrogen or loses electrons or gains oxygen can be termed as oxidized
Therefore, Succinate has been oxidized.
2) Answer : C ( FAD )
Reduction : It is the process in which gain of electrons or gain of hydrogen or lose of oxygen occurs
In this reaction FAD is acceting two hydrogen to become FADH2.
The compound which gains hydrogen or gains electrons or loses oxygen can be termed as reduced.
Therefore, FAD has been reduced.
3) Answer : C ( FAD )
Oxidiziing agent : The compound which remove hydrogen from another substance or give oxygen to another substance.
Here, FAS is removing hydrogen atoms from Succinate so that succinate can donate hydrogen to become oxidized.
so, FAD is the Oxidizing agent.
4) Answer : A ( Succinate )
Reducing agent : The compound which give hydrogen to another substance or remove oxygen from it.
Here, Succinate is giving hydrogen atoms so that FAD can accept to become reduced.
so, Succinate is the Reducing agent.
Oxidising agents give oxygen to another substance or remove hydrogen from it.
