Peroxidases Reduce Peroxides Using Various Electron Acceptors

Question

Hello,

I have just read this in Harper Biochemistry book :

Peroxidases Reduce Peroxides Using Various Electron Acceptors :

In the reaction catalyzed by peroxidase, hydrogen peroxide is reduced at the expense of several substances that act as electron acceptors, such as ascorbate (vitamin C), quinones, and cytochrome c.

I think, it is false, isnt it?

The enzymes reduce Peroxide and to do this they should use the other substances as Electron donors, not as electron acceptors.



What do you think?

Answer 1

I think you are correct.

It is true that peroxidases reduce peroxides.

It is not true that they use various electron acceptors. Rather they use various electron donors, which then themselves become oxidized,
