I need to know which school of your confusion I should go back to! What school can teach how the word "mimic", which means to imitate, can possibly be applied between a process that produces hydrogen and one that does NOT, that is, one process that does one thing imitating the other process that does not do that at all! If you could give us all a big hint as to what you think "mimic" means, that would be a big help, because, being well versed in English, I do not have a clue what you are trying to say!!!
