- Based on the definition of kcat, substitute a value that can be measured and yet still represents the value associated with the original concentration of the R. What would the rate or velocity of the reaction be equal to under these circumstances? How can cells increase Vmax? What variable that we could change would directly impact Vmax? Would the value of KM be affected by the ways you determined that Vma,x could be increased? What does this indicate about KM? Thinking about how catalysts work, about the Michaelis-Menten Equation, and the definition of kcat, what specifically does the enzyme change in the reaction mechanism to increase the rate? If an enzyme follows the 2 step mechanism proposed by Michaelis-Menten, what do you know about this enzyme? Be very specific and comprehensive. Please answer very soon will give rating surelych Select all statements that are correct. Note there might be more than 1 correct statement. From the Lineweaver-Burk plot the equilibrium constant (Keq) can be obtained The Lineweaver-Burk plot gives a more accurate prediction for Vmax than the Michaelis- Menten plot The Lineweaver-Burk plot assumes that products and reactants are present at equal concentrations during the entire time of the reaction The Lineweaver-Burk plot shows velocity of reaction vs substrate concentration The Lineweaver-Burk plot shows 1/velocity of reaction vs 1/substrate concentration O 20°C D) // E1. A gluscose trasporter in teh liver cell binds with Km of 40mM. Calculate what fraction of vmax the Vo operating when blood glucose is 10mM 2. Draw a Michaelis-Menten kinetic curve and identify Vmax and Km. Indicate on the curve where the reaction is first order, where the reaction is zero order, where the reaction operates at half-saturation, and the range where most enzymes operate Be very clear about your labels.

For competitive inhibition The Michaelis-Menten equation becomes Vo=Vmax[S]/(aKm+[S]) Put the Michaelis-Menten equation for competitive inhibition in the Eadie-Hofstee format. The Y-intercept of this plot will be
- The Michaelis-Menten equation models the hyperbolic relationship between [S] and the initial reaction rate Vo for an enzyme-catalyzed, single-substrate reaction E + S ES → E + P. The model can be more readily understood when comparing three conditions: [S] > Km- Match each statement with the condition that it describes. Note that "rate" refers to initial velocity Vo where steady state conditions are assumed. [Etotal] refers to the total enzyme concentration and [Efree] refers to the concentration of free enzyme. [S] > Km Not true for any of these conditions Almost all active sites will [ES] is much lower than [Efree]. be filled. The rate is directly proportional to Increasing [Etotal] will increase [S]. Km: Adding more S will not increase [Efree] is equal to [ES]. the rate.when saturated with substrate, an enzyme has a maximum initial rate of 110mumoles of substrate converted to product per second. At a substrate concentration of 100mu M, the same enzyme converts substrate to product at a rate of 0.010mmoles/ sec. Assuming that Michaelis - Menten kinetics are followed, calculate the reaction rate when substrate concentration is 2x10^-3M.An enzyme that follows simple Michaelis–Menten kinetics has an initial reaction velocity of 10 µmol⋅min−110 µmol⋅min−1 when the substrate concentration is five times greater than the ?M.KM.
