What is the role of glucose, which is added to a minimal medium? Use the appropriate vocabulary

Three different strains of Escherichia coli, respectively A, B, and C have been inoculated in three
different media, namely I, II, and III, and the growth of each bacterial strain has been followed by
spectrophotometry (Figure 1).
