DI LUS his tell you about the T U SHIP Between substrate) and enzymes with high KM values? With low Km values? Make a generalization. Occurs when we know [s] must be equal to KM, Km refers to binding affinity of enzyme 10 Substrate - higher km- tow binding affinity - WoW Km= high binding Affinity [5]= 1.5.6 = 1.75 5. a. What is the Ky value as you can estimate it from Graph 1? S pe =AY-1.75 -0_1.17 13.61...
will rate thanks Q1. WHAT ARE ENZYMES? HOW DOES ENZYME-SUBSTRATE BINDING TAKES PLACE? Q2. IN MICHAELIS -MENTEN GRAPH, WHY DOES THE CURVE REACHES PLATEAU? Vmax Reaction velocity (v) Vm/2 Km Substrate concentration (S) Q3. IN MICHAELIS MENTEN GRAPH, HOW WOULD YOU INCREASE VELOCITY BEYOND Vmax? Q4. SMALLER VALUE OF THE MICHAELIS CONSTANT (Km) REFLECTS HIGHER EFFICIENCY OF THE ENZYME. (TRUE/FALSE).
Question B1. The binding of a substrate (S) to an enzyme (E) can be described by the equilibrium E + S 4 ES At 273 K the equilibrium constant for this reaction has been found to be 0.134 for a particular substrate and enzyme. (a) Calculate the standard Gibbs energy change for the binding reaction at 273 K. [1 mark] (b) Calculate the free energy change for the reaction when the concentrations of the species at 273 K are: [E]...
What kind of kinetics is observed in an enzymatic reaction, under conditions where the substrate concentration is much higher with respect to KM ([S] >> KM)? Assume that a monomeric and non-allosteric enzyme is considered. A. Cooperative B. First Order C. Zero Order D. The systerm is at equilibrium and no reaction occures E. Second Order
Need help with number 13! I already asked about number 12. The inverse velocity and inverse substrate concentration relationship for an enzyme-catalyzed reaction is given below V Vmax Vmax S For the hydration of CO2 catalyzed by carbonic anhydrase, it was determined experimentally that (dm s mol 4023.9+ 39.934 at a total enzyme IS] concentration of 2.32 × 10-y mol-dm- What is the value of the Michaelis constant KM for this enzymatic reaction? (B). 9.92x103 mol dm3 (D). 100.8 mol...

Determine the oxidation rate at [S] = 50 microg/l.
What is the rate of an enzyme catalyzed reaction if the Vmax is 100µmol S→P/min and the Km is 7 mM and the substrate concentration is 11mM? Is the enzyme working at Vmax? What if the substrate concentration is raised to 25mM?
