Chapter 3, Problem 17P
Interpretation Introduction

(a)

Interpretation:

The non-equilibrium concentration of ethanol in yeast cells should be calculated.

Concept introduction:

The standard Gibbs free energy change is related to concentration of all the species involved in the reaction as follows:

ΔG = ΔG0 + RT ln Q

Here, ΔGo is standard Gibbs free energy change

ΔG is Gibbs free energy change

R is Universal gas constant

T is temperature

Q is reaction quotient

Interpretation Introduction

(b)

Interpretation:

The value of ΔG of the following reaction at pH = 7.4 and 370C should be calculated.

glucose + 2ADP + 2Pi + 2NAD+  2Pyruvate + 2ATP + 2H2O + 2NADH + 2H+

The preferred substrate is T because the enzyme half-saturates at 7.00 mM for T, but requires 28.0 mM for U, and 112 mM for S. b Question Content Area The rate constant k 2 with substrate S is 9.60×107 sec-1, with substrate T, k 2 = 6.00×104 sec-1, and with substrate U, k 2 = 2.40×106 sec-1. Calculate the catalytic efficiency with S, T, and U. Catalytic efficiency with S =  Catalytic efficiency with T =   Catalytic efficiency with U =   Does enzyme A use substrate S, substrate T, or substrate U with greater catalytic efficiency?
Fumerase catalyzes the conversion of fumerate to malate. fumerate + H2O ⇋ malate The turnover number, kcat, for fumerase is 8.00×102 sec-1. The Km of this enzyme for fumerate is 5.00×10-3 μmol mL-1.   a   In an experiment using 2.00×10-3 μmol·mL-1, what is Vmax?
Suppose you wanted to make a buffer of exactly pH 7.00 using KH2PO4 and Na2HPO4. If the final solution was 0.18 M in KH2PO4, you would need 0.25 M Na2HPO4. Now assume you wish to make a buffer at the same pH, using the same substances, but want the total phosphate molarity ([HPO42−]+[H2PO−4]) to equal 0.20 M. What concentration of the Na2HPO4 would be required?
