Consider the following statement “The tests (S) are easy iff you use your theorems sheet (T) or memorize the theorems (M) and attend zoom classes (Z) and read review practice assignments (A) before the midterm”   Which of the following is the equivalent Boolean Expression as read as is from the statement (no simplification)? [BooleanExp]   Which of the following is the proper simplification to a sum of product (sop) of the Boolean Expression? [BooleanSoP] What property allows you to do the simplification from your Boolean Expression to sop in the previous question? [SoPproperty] What property tells you that the order of the inputs/variables in your sop simplification does not change the output?  [Orderproperty] Which of the following properties would you use if you had to find the Inverse of your Boolean Expression? [Primeproperty] If you were to do a truth table for your Boolean expression how many input(s) and which will it/they be? [TruthInput] If you were to do a truth table for your Boolean expression how many output(s) and which will it/they be? [TruthOutput] If you were to use a k-map for your Boolean expression instead of the properties, how many k-map(s) you would use to simplify? [kmapsize]

The mathematical expression for the change in free energy of a system is G =H – TS. Which of the following is (are) correct?

During a laboratory experiment, you discover that an enzyme-catalyzed reaction has a ∆G of -20 kcal/mol. If you double the amount of enzyme in the reaction, what will be the ∆G for the new reaction?

A chemical reaction that has a positive G is best described as _____.

Use the following information to answer the questions below.A series of enzymes catalyze the reaction X  Y  Z  A. Product A binds to the enzyme that converts X to Y at a position remote from its active site. This binding decreases the activity of the enzyme.With respect to the enzyme that converts X to Y, substance A functions as _____.

One characteristic of life and living systems is that they are able to adapt. In general, cells interact with other cells and their environment through the action of their _____.

Integrins are integral membrane proteins. They are often attached to _____.

Actin filaments have polarity. This means that the two ends can be identified due to structural differences. The plus end is the end to which subunits are added more rapidly, or the end of polymerization. Which of the following would enable you to identify the plus end of actin filaments?

How might a change of one amino acid at a site, distant from the active site of an enzyme, alter an enzyme’s substrate specificity?
