I'm studying metabolic networks from a bioinformatics point of view, but I guess my question is pretty biological so I thought that maybe here I could get the best answers.
So, as the title says I was wondering, if I have one metabolite that is involved in two different reactions as reactant, is it possible that they both start at the same time at a certain point? I'm assuming that, in order to fire, the reactions need a certain amount of that metabolite, so if there is enough concentration to make both start, can the two reactions actually start in the same exact moment? What if the concentration of the metabolite is not enough to "satisfy" both?
Between the lines, are reactions mutually exclusive with respect to the shared metabolite or not?
In my mind, the quickest of the two gets the amount that it needs from the metabolite and the other one will just wait for the latter to have again enough concentration, is this intuition correct?
If you think this question is not appropriate, I will delete it and ask somewhere else. Any suggestion, also books or similar about the topic, is welcome!
I'm a computer scientist and I know just the basics of molecular biology, but I think that my job is mainly speaking to biologists in order to find solutions to different problems, so this is the reason why I chose to write here basically.
