I need the answer as soon as possible The ideal temperature for an enzyme,Enzyme A, is 34.5 degrees Celsius. Km =15.0 M, Vmax = 12.0 M/s were measured asenzyme kinetic parameters.The temperature for an enzyme kineticexperiment has been raised to 36.5 degreesCelsius. When the findings are revealed,what will happen? Plot the graphs asoverlaying figures for comparison andinclude at least five data sets prior to andafter the temperature was raised.

Enzymes are biocatalysts which increase the rate of biochemical reactions. Enzymes will not catalyze…

An enzyme that follows Michaelis-Menten kinetics has a KM value of 10.0 μM and a kcat value of 206 s−1 . At an initial enzyme concentration of 0.0100 μM , the initial reaction velocity was found to be 1.07×10−6 μM/s . What was the initial concentration of the substrate, [S] , used in the reaction ? Express your answer in micromolar to three significant figures..

Idris has successfully extracted enzymatic proteins from the fish viscera (intestines and stomach). After homogenization and centrifugation, he managed to pool the crude enzyme extract. He is characterizing the enzymes. Please help Idris by answering the followingquestions: (a) How do I run the experiment to find the kinetic properties of the enzyme, KMand Vmax? (b) The enzyme decreased in activity in the presence of NaCl. How do I find out if NaCl is a competitive or non-competitive inhibitor? Explain.

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.

Most of the enzyme reactions followed the mathematical kinetic plots suggested by Michaelis-Menten plots: Define Vmax and KM in the equations.
Lineweaver-Burk plots of enzyme kinetics for the reaction, S <-> P, has the following features: 1/v is zero when 1/[S] equals -40 liter mole^-1; 1/[S] is zero when 1/v equals 2.0 x 10^5 min mole^-1. What are the Vmax and Km?
You obtain a calculated Vmax of 4.26uM/s and a Km of 122.5uM from a kinetics experiment performed using 0.5uM enzyme. What is the catalytic efficiency of this enzyme?
An enzyme that follows simple Michaelis–Menten kinetics has an initial reaction velocity of 10 µmol⋅min-1 when the substrate concentration is five times greater than the KM. What is the Vmax of this enzyme in µmol⋅min−1?
Two experiments were performed with the enzymeribonuclease. In experiment 1 the effect of increasingsubstrate concentration on reaction velocity was measured.In experiment 2 the reaction mixtures were identical tothose in experiment 1 except that 0.1 mg of an unknowncompound was added to each tube. Plot the data accordingto the Lineweaver-Burk method. Determine the effect of theunknown compound on the enzyme’s activity. (Substrateconcentration is measured in millimoles per liter. Velocity ismeasured in the change in optical density per hour.)
