Question

I don't know if I'm correct, but does glucose acts as competitive inhibitor here (Vmax is unchanged, Km increased)? Also, just to be sure, is that what they are asking for in the question? 

Thank you. 

In another study, inhibitory effects of
glucose on the activity of a completely
different enzyme, called CyntA, was
investigated. Some results from this work
are sketched in Figure 2.
State what type of regulatory effect glucose
appears to exert on CyntA and discuss very
briefly what characterizes this type of
enzyme regulation.
