explain the regulatory mechanisms related to enzyme specificity. In your answer address: function of enzymes, illustrates and identify key characteristics of the kinetic curve.
Homework Answers
Enzyme are proteins that speed up reactions by reducing the activation energy without being consumed in the reaction.
The functions of enzyme are :-
- They accelerate reactions
- Promote metabolism
- Allow regulation of metabolic pathways
Kinetic curve - concentration versus time curve ,rate of the
reaction is obtained from the slope of kinetic curve

a) For most enzymes, the Km is closely related to the affinity of the enzyme for its substrate(s). Which has higher affinity, an enzyme with a low Km, or an enzyme with a high Km? Justify your answer. b) True or false: at a pH equal to its pKA, the average charge on an ionizable amino acid sidechain (such as lysine's ε-amino group) will be zero. c) Titration of isoleucine by a strong base, for example NaOH, reveals two pK’s....

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...
