I'm sorry you feel upset about the status change of your post. I have commented under your post and I will cite it here for completeness:
[...]'Homework' is used as a label to more generally describe Qs that are devoid of prior research. It borders on 'too broad', another much used close-reason. Your Q is also too broad. Prior research on OP's side can aid to lessen the scope and pinpoint a focused question. As of now it seems like a general metabolism question that warrants discussions on enzymes, co-factors, magnesium as a co-factor, the difference between general house-hold enzymes involved in glycolysis and CAC versus those used in detox mechanisms. It needs prior research and focus.
See for instance this recent question, which is a good example of a Q where the scope has been narrowed down effectively by adding prior research.
Regardless whether you agree with it or not, please stop calling the mods a troll. Further, David is neither a mod (mods have a ♦ behind their name), nor a troll. Instead, he is a long-term, hi-rep user who has earned many mod-privileges on this site. David can admittedly be a bit direct at times, but mind that he has been with us for a long time and knows better than most what the conventions of this site are and how these conventions came into being. Therefore I agreed with his close-vote, namely that the question is considered to be homework. The tag homework is indeed sometimes kind of unfortunate, as I have personally experienced here as well when a Q of mine was close-voted for that same reason while doing a postdoc :) There have been meta discussions on this topic and they haven't resulted in another close-reason as yet. We are [kind of] working on that.
