Consider an enzyme catalysed reaction treated with inhibitor. Enzyme kinetic was analysed with Eadie Hofstee equation. A plot of V0 versus V0/[S] for an enzyme-catalyzed reaction is shown below. The control curve was obtained in the absence of inhibitor. Which effect is shown on the enzyme activity when an inhibitor is added to the reaction mixture?

Consider the scale up of a fermentation from a 10L to 10000L while maintaining geometric similarity. Agitation speed was maintained at 500 rpm in the 10L fermenter. If scale up is done based on constant tip speed, then the agitation speed in the larger reactor should be 

rpm.
