You are conducting a biochemical experiment with an enzyme that has optimal activity at pH = 6.50. You decide to use carbonate (pKa1 = 6.38, pKa2 = 10.30) as the buffer to keep the pH stable throughout the enzymatic reaction. (Recall that the formula for carbonic acid is H2CO3.) You prepare a 0.4 M solution of carbonate buffer at pH = 10.50. Calculate the concentrations of the major carbonate species in your solution. Show your calculations.

Two different proteins X and Y are dissolved in aqueous solutionat 37 °C. The proteins bind in a 1:1 ratio to form XY. Asolution that is initially 1.00 mM in each protein is allowedto reach equilibrium. At equilibrium, 0.20 mM of free X and0.20 mM of free Y remain. What is Kc for the reaction?
EXPLAIN IN 3-5 SENTENCES:1. What are the tissue sources of Alkaline phosphatase? 2. What are Regan and Nagao isoenzymes? 3. State other approach of ALK determination through the existing isoenzymes.
Many enzymes are inhibited irreversibly by heavy metal ions such as Hg2+, Cu2+, or Ag+, which can react with essential sulfhydryl groups to form mercaptides:The affinity of Ag + for sulfhydryl groups is so great that Ag+ can be used to titrate —SH groups quantitatively. To 10.0 mL of a solution containing 1.0 mg/mL of a pure enzyme, an investigator added just enough AgNO3 to completely inactivate the enzyme. A total of 0.342 μmol of AgNO3 was required. Calculate the minimum molecular weight of the enzyme. Why does the value obtained in this way give only the minimum molecular weight?
