I have the following question in systems biology: a) Draw a graph showing the relationship of growth (Vbio) and Vefni for the system here. (Let the horizontal axis represent Vbio and the vertical axis represent Vefni)
My first thought was that it would simply be straight line from (0.5,0.5) to (1,0). But now I'm thinking that I have to take V4 into account as well.
b) Determine one or more reactions that are such that if they are taken out the production of M4 is coupled to growth (growth-coupling). Draw a graph showing the relationship Vbio and Vefni for the mutant.
Here I thought it would be V1 and V4. I'm not sure though because I haven't found a good explanation for what growth-coupling is exactly.
c) Why is it desirable to couple chemical production to growth? i.e. what advantages do those systems have over the ones where no such coupling is present?
Here I have no idea.
