Interpretation Introduction

(a)

Interpretation:

V0 versus pH curve when the substrate concentration is much greater than the enzyme KM should be drawn.

Concept introduction:

KM is the Michaelis constant which is the substrate concentration when the reaction rate is half of the maximum rate achieved by a system. Michaelis constant is a measure of its binding affinity to a substrate. The higher the Michaelis constant, the lower affinity for its substrate. That means an enzyme with lower KM needs a higher concentration of substrate to achieve Vmax.

Interpretation Introduction

(b)

Interpretation:

V0 versus pH curve when the substrate concentration is much less than the enzyme KM should be drawn.

Concept introduction:

KM is the Michaelis constant which is the substrate concentration when the reaction rate is half of the maximum rate achieved by a system. Michaelis constant is a measure of its binding affinity to a substrate. The higher the Michaelis constant, lower affinity for its substrate. That means an enzyme with lower KM needs a higher concentration of substrate to achieve Vmax.

Interpretation Introduction

(c)

Interpretation:

The pH at which the velocity will equal half of the maximal velocity attainable under these conditions should be determined.

Concept introduction:

KM is the Michaelis constant which is the substrate concentration when the reaction rate is half of the maximum rate achieved by a system. Michaelis constant is a measure of its binding affinity to a substrate. The higher the Michaelis constant, lower affinity for its substrate. That means for an enzyme with lower KM needs a higher concentration of substrate to achieve Vmax.

From the reaction data below, determine whether the reaction is first order or second order and calculate the rate constant. Time (s) 0 Reactant (mM) 5.4 1 4.6 2 3.9 3 3.2 4 2.7 5 2.3 Only a plot of In[reactant] versus t gives a straight line, so the reaction is first order . The negative of the slope, k, is 0.171
Hair grows at a rate of about 20 cm/yr. All this growth is concentrated at the base of the hair fiber, where a-keratin filaments are synthesized inside living epidermal cells and assembled into ropelike structures. Two-chan 14 Protofilament 20-30 A Two-chain Intermediate flament -Protob Protofilament Cross section of a hair The fundamental structural element of a keratin is the a helix, which has 3.6 amino acid residues per turn and a rise of 5.4 A perlum. 54A (36) Amino terminus Carbon Hydrogen Oxygen Nitrogen group Carboxyl terminus Assuming that the biosynthesis of a helical keratin chains is the rate-limiting factor in the growth of hair, calculate the rate at which peptide bonds of a-keratin chains must be synthesized (peptide bonds per second) to account for the observed yearly growth of hair. 0422 rate of peptide bond formation: Income bonds/s
Specific rotation is a measure of a solution's capacity to rotate circularly polarized light. The unfolding of the a helix of a polypeptide to a random conformation is accompanied by a large decrease in specific rotation. Polyglutamate, a polypeptide made up of only 1-Glu residues, has the a helix conformation at pH 3. When researchers raise the pH to 7, there is a large decrease in the specific rotation of the solution. Similarly, polylysine (1.-Lys residues) is an a helix at pH 10, but when researchers lower the pH to 7 the specific rotation also decreases, as shown in the graph. a Helix Specific rotation Poly(Glu) a Helix Random conformation Poly(Lys) Random conformation T + ° 2 4 6 В 10 12 14 PH Complete the statements about the molecular mechanism for these changes in specific rotation. Increasing the pH of a polyglutamate solution from 6 to 7 causes the carboxyl group of each glutamate residue Comed Artwer lose a proton. The negatively charged groups in each glutamate residue…
