The graph below shows the fluidity of fatty acids in a phospholipid bilayer as a function of temperature. Cholesterol helps prevent extremes in fluidity by both “stiffening” (at T>Tm) and “liquefying” (at T

When congress and the president have concluded that the economy is in a recession,  they can use Fiscal Policy to

The kinetics data of an enzyme E  (whose concentration is maintained constant at a level of 1 mM (=10-6 M)) is shown in the table below. A double reciprocal (Lineweaver-Burk) plot was generated from this data, also shown below.  Blank #1: Determine the Vmax (include the units) for this enzyme. Blank #2: Determine the KM (include the units) for this enzyme. The experiment above was repeated twice more, once adding 10 mM of inhibitor A, and the second time adding 10 mM of inhibitor B (separately). The Lineweaver-Burk plots in the presence of these inhibitors are indicated by “+A” or “+B” in the plot below.  Blank #3: What type of inhibitor is A? Blank #4: What type of inhibitor is B? Blank #5: Which of the two curves below corresponds to inhibitor A? (1 or 2)      

Make a drawing of a Red Panda in a basic paint program.  Upload the file here.

Text (no question) allows instructors to give information about a part of the test.  Really, it could say anything, but usually I see it as giving instructions to use certain information for certain questions.   The following 5 questions will be about Unicorns.

Essay Questions generally take more work than the other questions, so usually they will have a higher point value depending on how hard the instructor thinks the question is.   Write an essay about how awesome Red Pandas are.

A person’s economic status is considered in setting bail?  True / false

Write the equation of the line assing through (2, 5) and (1, 8).

Polypeptide chains can fold into regularly repeating structures such as an alpha helix, a beta pleated sheet, or a beta turn. Match the following information about a particular polypeptide with one of these secondary structures. 

Below are postulated protonation states of histidine. pKa values for histidine are 1.8 (a-COOH), 9.2 (a-NH3+), 6.0 (R group). Blank #1: List the letters of the 4 states that do NOT form at any pH, separated by commas.  Blank #2: List the letter of the zwitterion.  For blanks #3 -> #6:  For each of the 4 states that do form (the four you did not list in Blank #1) list the following: the letter of that state, and the approximate pH range in which that state predominates (>90%). Make sure to only do one state per blank. Separate the letter and pH with a comma (for example: B, 3.3 to 5.3 or B,
