3) Enzyme kinetics are determined under initial rate conditions, wherein the initial substrate concentrations changes very little, because:
(A) Products do not accumulate and inhibit the forward reaction
(B) Enzymes are unstable under most assay conditions, and rapidly lose activity
(C) The substrate concentration does not change appreciably and so does not create an additional variable
(D) All of the above
(E) Some of the above
Homework Answers

Under what circumstances does an enzyme catalyzed reaction rate resemble a non-enzyme catalyzed reaction? At very low concentrations of substrate (Km is greater than S) the Michaelis-Menton equation can be simplified to? At very high concentrations of substrate, the Michaelis-Menton equation can be simplified to? How do you determine the initial rate of reaction

An irreversible reaction A + B products is studied under conditions where the initial concentrations of A and B are equal. Under these circumstances, a graph of ln([A]) as a function of time is linear. What is the order in A? (A) Zeroth order B) First order (C) Second order (D) The order in A cannot be determined based on the information given. Doesn't the first order reaction kinetics say that the graph of ln[A] vs t gives a...

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...
