I approved an edit on this question where the metabolism tag was added. I am not 100% sure that I would agree that the essence of the question is about metabolism, but I did not disagree strongly enough to reject the edit either.
That then raised the question of what the appropriate use of the metabolism tag is. The tag description states:
The set of chemical reactions that happen in the cells of living organisms to sustain life.
Technically any question related to a cellular process could be classified as cell metabolism, but metabolism may not be at the heart of the question. Nature's Scitable gives the following definition:
A cell's daily operations are accomplished through the biochemical reactions that take place within the cell. Reactions are turned on and off or sped up and slowed down according to the cell's immediate needs and overall functions. At any given time, the numerous pathways involved in building up and breaking down cellular components must be monitored and balanced in a coordinated fashion. To achieve this goal, cells organize reactions into various enzyme-powered pathways.
So my question is when is it appropriate to tag a question as being a question about metabolism and when should the question not be tagged with the metabolism tag?
Would we want to reserve the tag for only those questions that dealt with cellular processes such as Glycolysis, The Citric Acid Cycle, Oxidative Phosphorylation, etc. or is any question about cell function fair game for the tag?
A secondary question would be is the question that I linked above an example of a question that would warrant the metabolism tag.
Thank you in advance.
