In the space draw a curve representing the energy in a reaction that takes place in the absence of an enzyme and superimpose the curve for a reaction that proceeds with the aid of an enzyme.

A student determined the Km, Vmax and turnover number (kcat) for an enzyme by performing reactions with varying amounts of substrate and a concentration of enzyme at 10nm   The student then decided to repeat the reaction with the same substrate concentration but with increased enzyme concentration to 20nm.   Would the following increase, decrease or stay the same?   Km Vmax Kcat

Write a chemical equation for the reaction catalyzed in model one —— Chemical Reaction I wrote ( Lactase —> Glucose + Galacose ) 1. Referring to the chemical reaction you wrote for the question above is lactase a reactant or product or neither explain how you know. Q2.  describe the role of the enzyme lactase played in the reaction. Q3.) what do you think could happen to the enzyme lactase at the end of the reaction Q4.)  enzymes play a very specific roles in cells and will work on specific substrates, for example, well liked his breaks down like lactose, lipase is an enzyme that breaks down lipid molecules. Using the base and lactase examples describe how are most enzymes are named. Q5,) suppose a model of a different disaccharide sucrose would like to be able to break down sucrose explain your answer.

Please handraw this graph with all the necessary detailed information:   Imagine that I text enzyme rate for four different temperatures: 10 degrees celsius, 20 degrees celsisus, 30 degree celsius, and 40 degree celsius, in separate tubes. The enzyme appears to work faster as temperature increases, but completely ceases activity at 40 degrees celcius. Sketch a graph to show this outcome, but here you will graph product formation (nmoles/mL) vs. time (minutes). The graph should be 4 lines and HANDDRAWN. Include a legend if necessary. You do not need precise quantitivate values, but most show the correct trends on the graph.
