Reset Help complexEnzymes catalyze reaction by stabilizing the If the enzyme binds to the substrate too Thus, the enzyme binds best to induced fit lock and key transition state well, the activation energy for the catalyzed reaction the and the activation energy In the model, the enzyme binds to the most efficiently decreases In the model, both the enzyme and change their structure upon remains about the same binding in a way that favors the formation of the increases Thus,...
7. Explain the basics of enzyme function and structure (sketch an enzyme and label the active site, allosteric site, where the substrate binds, where competitive and non-competitive inhibitors bind). Include how many different reactions can be catalyzed by an enzyme and how many times an enzyme can catalyze that reaction.

What is the correct answer? Please explain. Consider the kinetic plot of an enzyme catalyzed reaction to the right. Which of the following is not correct concerning the this enzyme? a. Compound stabilizes the ''R state'' of this enzyme. This enzyme exhibits ''cooperative binding'' of the substrate. This enzyme is probably composed of multiple catalytic and regulatory subunits. d. This enzyme is composed of a single polypeptide chain with one one binding site for substrate. Compound binds to a regulatory...
please answer a,b and c. 4. Consider when enzyme E binds to Substrate Sassuming Michaelis-Menten kinetics kz[E]. [S] R= [S] + km a) What is the rate when [S] = km? b) What is the maximum rate (which is achieved when [S] >>> km) c) The rate of the reaction vs substrate concentration is given by the graph below. Indicate the VALUE of half of the maximum rate (Romex/2) and ku using the equations you derived in part a and...
13. Suppose a second enzyme binds the substrate even more tightly than the enzyme shown in model 1 (the ES complex is more stable than the one shown in graph B). Draw this new E.S complex on graph B. What happens to the magnitude of the activation energy, AGact? 14. Suppose a third enzyme binds the transition state even more tightly than the enzyme diagramed Model 2.
