- Question 11. // Hint: Isoelectric focusing separates proteins based on their pI values, and can separate proteins that only differ by a net charge of ±1.±1. Recall that an amino acid residue with a negatively charged R group has a relatively low isoelectric point (pI) where it has zero net charge. Likewise, an amino acid residue with a positively charged R group has a relatively high isoelectric point (pI) where it has zero net charge. Order from Low pH to High pHQUESTION 22 When the final product of a series of enzymatically-catalyzed reactions binds to the first enzyme in the pathway to limit its production, it generally uses ___ because the structure of this final product is generally not similar to that of any of the enzyme's normal substrates.
