Q1)
A) True or False? Proximity and orientation effects are a
feature of all enzyme-catalyzed reactions. Explain your
reasoning.
B) PMSF (phenylmethylsulfonyl fluoride) is an inactivator of
serine proteases. It is commonly used in the production of protein
for experimental study; it prevents cellular proteases from
digesting the protein of interest
True or false? Lowering the pH of the solution would alter binding
by PMSF. In a single sentence, explain how you arrived at your
answer.

Which of the following statements are true regarding chemical
reactions? T = true and F = false.
A) the more negative the ΔG, the further towards completion the
reaction will proceed before equilibrium is reached.
B) only a system not at equilibrium can perform work.
C) for most biochemical reactions in a metabolic pathway,
equilibrium is rarely reached.
D) in a closed system, a chemical reaction will proceed
spontaneously until the reactants and products are in equal
concentration.

Molarity is the concentration of chemical solutions. It
is the number of moles of solute dissolved in a liter of solution.
It is denoted by M, and the unit is moles per liter, which
can be written as molL.
molarity of a solution= moles of soluteliters of solution
Molality of a solution is the amount of solute divided
by the mass of the solvent (not the mass of the solution). It is
also defined as the number of moles of...
