Hello, students.

Now, in this question, with respect to the electron transport chain, which do you think, which of these five molecules do you think will have the highest reduction potential? to understand that, first we need to know what reduction potential means, right? so, it basically means that the ability to accept electrons or to lose the protons is what is known as the reduction potential.
00:30
Right? the potential it has to lose the protons or gain the electrons is what is known as the reduction potential.
00:40
So in this case, if we consider the first two cases, that is iron that is found in the fes centers of complex 1 or complex 2.
00:48
Both of them are wrong here because here you will observe iron is the one that will get oxidized, right? that means it will lose electrons, not gain electron.
00:58
So obviously you will observe the first and the second one to be wrong here.
01:02
What about the third one? ubiquinone.
01:05
Now ubiquinone upon reduction will convert to ubiquinol.
01:11
What will it convert to? it will convert to ubiquinol, right? and you will observe fad to form fadh2, right? that is the reduction process that you will observe with respect to both the cases...
