A biochemist studying the activity of the enzyme triose phosphate isomerase (TPI) in a species of Drosophila wants to know if the mean activity of this enzyme is the same at ??=5 and ??=8. Enzyme activity (?????) ?? = 5 11.1 10.0 13.3 10.5 11.3 ?? = 8 12.0 15.3 15.1 15.0 13.2 a. Given the above data and assuming enzyme activities are normally distributed, determine if the mean activities of TPI are significantly different at these two pH levels....

A solution of .1M fructose-1,6-bisphosphate is treated at 37degrees C with aldolase and triose phosphate isomerase under conditions of pH and ionic strength where both enzymes are active. What will be the concentration of glyceraldhyde-3-phosphate when equilibrium is reached? deltaGo'= +23.8 kJ/mol for fructose-1,6-bisphosphate -> DHAP and GAP delta Go'= +7.5 kJ/mol for DHAP -> GAP

Descriptions of enzyme mechanisms often contain the terms
reaction intermediate, transition state, and transition state
analogue. The terms intermediate and transition state both describe
chemical species along the reaction pathway, but there are
important distinctions between the two. Transition state analogues
are often used in enzyme mechanism studies. Match the phrases to
the term that they describe. Scroll down to see all the items.

Using the National Center for Biotechnology Information Web site () find the sequence of the enzyme triose phosphate isomerase from E. coli. Use this sequence as a query for a protein-protein BLAST search. In the output, find the alignment with the sequence of triose phosphate isomerase from human beings (Homo sapiens). How many identities are observed in the alignment?

2. The table below contains data on the enzyme activity of mannose-6-phosphate isomerase (MPI) for three different genotypes (SS, FS, FF) in the amphipod crustacean Platorchestia platensis. Because the effects of sex are not known, specimens were classified by sex. Conduct a two-way ANOVA on this dataset. Test for effect of genotype, the effect of sex, and whether there is an interaction effect between two factors. Show all calculations and state your conclusions.

In a key reaction of glycolysis, dihydroxyacetone phosphate (DHAP) is isomerized into glyceraldehydes 3- phosphate (G3P) by the action of the enzyme triose phosphate isomerase: Because delta G degree, is positive, the equilibrium lies to the left. Calculate the equilibrium constant for this reaction, assuming a temperature of 37 degree C. In the cell, depletion of G3P makes the reaction proceeds. What is the value of delta G if the concentration of G3P is kept at 1/100 of the value...
