- True or False Immobilization improves the stability of the enzyme. EnaLne, has a half-life of 10 days in free solution, but under identical conditions of temperature, pH, and medium composition, the measured half-life of a packed column is 30 days. The enzyme is immobilized in a porous sphere 5 mm in diameter.arrow_forwardA generalized enzyme active site is shaped like a hemisphere with a radius of 45Å. The active site holds the following amino acids in a homeostatic solution (pH = 7.38): -HAVARILKHAVARILKHAVARILK- Assuming the charge is distributed uniformly along the hemisphere, determine the force at which this active site acts upon a single ATP molecule at the center of the hemisphere.arrow_forwardSeveral factors contribute to enzyme catalysis.

- Explain why the very tight binding of a substrate to an enzyme is not desirable for enzyme catalysis, whereas tight binding of the transition state is desirable.arrow_forwardRuBP carboxylase is by no means an ideal enzyme. Describe some of the problems with its active site and its substrate specificity. If we compare the amino acid sequences of this enzyme from many different species, they are almost identical. What is the significance of this uniformity?arrow_forwardThe pKa for histidine is pKa = 6.1 while that for cysteine is pKa = 8.0 2. Assume that both histidine and cysteine are catalytic groups for a particular enzyme. Assume also that the side chain of cysteine must be in the deprotonated form. Estimate the pH at which the catalytic activity of this enzyme is the maximum and sketch a pH-activity graph.arrow_forward

- Enzymes are proteins that increase the rate of chemical reactions by lowering the energy activation required to facilitate the process. Explain the generalized and sequential enzyme mechanism of action (hint: from substrates to products).arrow_forwardThe breakdown of a complex carbohydrate into its monomeric unit can be described as an enzyme-catalyzed reaction that has a deltaG(∆G) of -90kcal/mol.

A solution of the enzyme hexokinase incubated at 450C lost 50% of its activity in 12 minutes, but when incubated at 450C in the presence of a very large concentration of one of its substrates, it lost only 3% of its activity in 12 minutes. Suggest why thermal denaturation of hexokinase was retarded in the presence of one substratesarrow_forward
