BIS103-002 Final Exam ___________________________________ 2 Winter 2004 Last, First 1. (23 pts) (a) (8 pts total, 0.5 pt per answer). There are two lists: a list of enzyme types (Column 1) and a list of co-factors (Column 2). Below the lists is a list of specific enzymes with two blank columns to their left. Place a letter in the spaces provided in the left most column that corresponds to the most correct enzyme type for the enzyme name given in that same row (Column 1). Also, for each enzyme, place a number in the spaces provided in the right-hand column that correspond the co-factor required for the enzyme (Column 2). One answer per line. Each enzyme name should have both a letter and a number. Each one may be used more than once. Column 1 Column 2 Put 1 letter from Column A in left blank column put 1 number from this column in the righthand blank column A. Oxidoreductase 1. Pyridoxal phosphate (PLP) B. Isomerase 2.
