Which of the following best describes the assumption made in steady state kinetic analysis?Group of answer choicesThe concentration of the substrate is decreasing.The concentration of the substrate is constant.The formation of the enzyme-substrate complex is the rate-limiting step.The concentration of enzyme-substrate complex is constant.The enzyme-substrate complex is quickly transformed into the product and free enzyme.

Which of the following statements is/are correct in enzyme kinetics, if S represents the substrate?Group of answer choicesAt very low substrate concentration, the rate of enzyme reaction is zero order with respect to [S].At all substrate concentrations, the rate of enzyme reaction is first order with respect to [S].At very high substrate concentration, the rate of enzyme reaction is first order with respect to [S].At very high substrate concentration, the rate of enzyme reaction is zero order with respect to [S].At all substrate concentrations, the rate of enzyme reaction is zero order with respect to [S].

According to the Michaelis-Menton kinetics theory, when a reaction is performed in zero-order kinetics:Please select the single best answer The substrate concentration is very low and the reaction rate is dependent on the substrate concentration The substrate concentration is in excess and the reaction rate is dependent on the enzyme concentration The enzyme concentration is in excess and the reaction rate is dependent on the substrate concentration The substrate concentration is equal to Km and the reaction rate is dependent on the enzyme concentration

Specific growth rate depends on substrate concentration (according to Monod kinetics) in the following wayGroup of answer choicesincreases with increasing substrate concentrationdecreases with increasing substrate concentrationreaches a maximum at high substrate concentrationsis independent of substrate concentrationis zero if substrate concentration is zerois half-maximal when the substrate concentration equals Ks

(True or False) Increasing the substrate concentration would infinitely increase the activity of an enzyme.Question 5Select one:a.Trueb.False

Which of the following statements is/are true of enzyme catalysts?Group of answer choicesThey bind to substrates but are never covalently attached to substrate or product.They increase the equilibrium constant for a reaction, thus favoring product formation.They increase the rate at which substrate is converted into product.They lower the activation energy for the conversion of substrate to product.To be effective, they must be present at the same concentration as their substrates.
