00:01 Hello students here the question is asking to identify the correct statement regarding nad plus.

00:09 So we should select or choose the correct statement regarding nad plus.

00:17 So what is nad plus? nad plus full form is nicotine amide nicotine amide adenine dinucleotide is known as this n -a -d plus so what is the structure of n -a -d -plus n h here one amide group is there and here ribosugar is attached with n adp okay so this is the structure so here it is positive charge on end and it will undergo both reduction as well as oxidation so it is in positive state hence it will take two electrons two electrons and one proton okay so one proton and two electrons it is getting reduction so reduction is take takes part here so what will happen this bone will migrate from here to here and this will come here one electron is taken by this one and the other electron is goes to here so we'll get hydrogen here so what will happen n bond bond here it is h and two electrons taking part so it will get a minus charge so here it is this positive charge is there and it will be after taking two electrons it will be h minus then it will migrate to here and then we will get here h and here my group will be here is a bond and also here one bond is there and also here as usual the remaining structure will be same.

02:37 So this is the oxidation form.

02:41 If it loses hydrogen and two electrons, then it can be nad reversible reaction.

02:49 It will get oxidation.

02:53 So it can undergo reduction by taking two electrons and one proton.

03:00 And after reduction, it will undergo oxidation by losing two electrons and one proton...
