Denaturation can occur if a protein is heated or undergoes changes in pH. Denaturation disrupts the secondary, tertiary, and quaternary structure of a protein. Would you expect the Biuret test to work on a protein that had been denatured? Why or why not?

Protein Denaturation: 1) If changing the pH of an enzyme solution greatly reduces the activity of that enzyme without precipitation, how could you tell in the lab if it were the result of denaturation or just going to a pH that is just not a good one for the enzyme? And how would a change in pH impact or even stop enzyme function without denaturation? (Consider the enzymes that are active in your stomach, such as pepsin-discussed in Wikipedia.) 2)...

Variations in temperature and pH can cause major changes to a protein. Explain how.

Describe the pH changes that occur in the two aqueous compartments of the mammalian mitochondria, the matrix and the inter membrane space, when the ETC has high flux. Describe the biochemical basis for these changes.

Topic: Protein Denaturation 1) What are the various levels of organization that any protein structure may have that gives it its 3D shape? Which of these changes during denaturation? 2) For each change made to a protein solution, how might it affect the interactions that are involved in a protein's shape? 3) What is the difference between precipitation of a protein and its denaturation? How might you tell the difference?

If a patient has a collapsed lung what changes to blood pH are likely to occur?...

If a patient has a collapsed lung what changes to blood pH are likely to occur? Explain why this might happen. How could the body compensate for these changes?

Changes in demographic outcomes can occur because of changes in within-group rates and/or changes in composition....

Changes in demographic outcomes can occur because of changes in within-group rates and/or changes in composition. First, explain what that sentence means. Then take the example of falling rates of death due to heart disease. How might changes in within-group rates account for that outcome? What about changes in composition? Can you think of any way to sort out the effects of changes in within-group rates vs. changes in composition?

The nature of federalism is dynamic. It undergoes changes as changes in the demands of society occur. What is the relationship between contemporary politics and trends in the size and power of the federal government? Many state governments argue that making federal funds dependent on state cooperation with national goals is “federal blackmail.” Why must the federal government use these financial incentives (and disincentives) instead of simply legislating that states do what the federal government wants? Does federalism retain substantial...

As 2 moles of sirenite is heated under a constant pressure of 1 atm it undergoes a solid phase transition, at a temperature of 750 K, from α-sirenite to β-sirenite. The molar specific heat capacity of sirenite varies with thermodynamic temperature, T, such that Cvm = 2.50 x 10-6 T^2 Jmol-1K-1. a) Calculate the entropy change of the sirenite between the transition temperature of 750 K and room temperature (300 K). b) By what factor does the number of accessible...
