You can Visit This Link for more important MCQs. b) In the presence of a uncompetitive inhibitor, the Michaelis-Menten equation becomes The initial velocity prior to enzymatic activity The concentration of substrate (moles/liter) needed to achieve 50% of the maximum The concentration of substrate at which all enzymes are being used (saturated) and it is producing at maximum effect. Steady states and the Michaelis Menten equation. by sthompson36_09398. Michaelis-Menten kinetics is used to describe the rate of a reaction catalyzed by an enzyme as a function of the substrate concentration. Next lesson. a. John Northrop. a) $$\frac{1}{V_0} = \frac{K_m}{V_{max} [S]} + \frac{1}{V_{max}}$$ This type of analysis is also commonly used to describe the rate of transporter-mediated translocation of ions and molecules across biological membranes.

Free PDF Download of CBSE Chemistry Multiple Choice Questions for Class 12 with Answers Chapter 4 Chemical Kinetics. Which of the following is true about Michaelis-Menten kinetics? T F Only the symmetry model of allosterism can be used describe a negatively cooperativite enzyme. In 6 minute, half of the substrate is used. K m is the substrate concentration needed to reach 50% of V max. Which of the statement is true regarding Km a) It is the measure of the stability of the ES complex b) It is the measure of the stability of the affinity of an enzyme for its substrate c) A high Km indicates weak substrate binding The Michaelis constant (Km) of an enzyme identifies the substrate concentration at which 50% of the enzyme active sites, on average, have substrate bound to them. remains rigid and does not change shape. B) â¦ $$V_0 = \frac{V_{max} [S]}{K_m+Î±’ [S]}$$ 12 hours ago. Which of the following statements about a plot of V0 vs. [S] for an enzyme that follows Michaelis-Menten kinetics is false? DNA. Which of the following is the correct Line weaver-Burk equation? b) Penicillin K m decreases with competitive inhibition. b) Inhibitor These are often vitamins. b) It acts by increasing the activation energy Sanfoundry Global Education & Learning Series â Biochemistry.
