The Michaelis-Menten equation models the hyperbolic relationship between (S) and the initial reaction rate V, for an enzyme-catalyzed, single-substrate reaction E+ S E S E+P. The model can be more readily understood when comparing three conditions: [S] << Km, [S] = Km, and [S] >> K. Match each statement with the condition that it describes. Note that "rate" refers to initial velocity Vwhere steady state conditions are assumed. [Exotal) refers to the total enzyme concentration and [Etre) refers to the...

10. Write a one-page summary of the attached paper? INTRODUCTION Many problems can develop in activated sludge operation that adversely affect effluent quality with origins in the engineering, hydraulic and microbiological components of the process. The real "heart" of the activated sludge system is the development and maintenance of a mixed microbial culture (activated sludge) that treats wastewater and which can be managed. One definition of a wastewater treatment plant operator is a "bug farmer", one who controls the aeration...
