Imagine that scientists have discovered an industrial pollutant that modifies the structure of a cell cycle checkpoint protein such that it loses its function. Cultured human cells exposed to this molecule divide at a rate double that of untreated cells. Based on these data only, one could conclude that the chemical is.

Penicillin is hydrolyzed and thereby rendered inactive by penicillinase (also known as Îē-lactamase), an enzyme present in some resistant bacteria. the mass of this enzyme in staphylococcus aureus is 29.6 kd. the amount of penicillin hydrolyzed in 1 minute in a 10-ml solution containing 10-9 g of purified penicillinase was measured as a function of the concentration of penicillin. assume that the concentration of penicillin does not change appreciably during the assay. penicillin(Ξm) amount hydrolyzed(nmol) 1 0.11 3 0.25 5 0.34 10 0.45 30 0.58 50 0.61 (a) plot v0 versus [s] and 1/v0 versus 1/[s] for these data. does penicillinase appear to obey michaelis-menten kinetics? if so, what is the value of km? (b) what is the value of vmax? (c) what is the turnover number of penicillinase under these experimental conditions? assume one active site per enzyme molecule.
