Fumarase is the enzyme that catalyzes the following reaction between fumarate and water to produce malate in cells. Which statement can be used as evidence that orientation of reactant molecules is part of the function of fumarase as a catalyst?
a. The active site of fumarase contains a histidine and a lysine that function as an acid and a base, respectively, during catalysis.
b. Fumarase does not use a coenzyme but requires one Fe2+ ion at its active site.
c. Fumarase binds one fumarate molecule and one water molecule the same way for every reaction.
d. Mutation of the active site lysine to other amino acids obliterates or severely reduces activity in fumarate.
e. Fumarase catalyzes both the forward and reverse reactions between fumarate and malate.

Zoe decided to measure the hand length of each of her classmates. first she marked a line across each student's wrist and lined up a ruler from this mark to the top of the middle finger to measure the length. then she recorded the measurements in the table below. marla did this the same way for each classmate, and then zoe used this ruler to measure each straight line and record the data below. this data is invalid. what is the most likely reason why it is invalid? the ruler is marked in centimeters, but zoe recorded data in inches. the range of lengths is too wide, so zoe must have misread the ruler. marla’s complicated measuring procedure was overly confusing. marla could have been inconsistent while drawing outlines of fingers.
