Question

Acetylcholinesterase is an enzyme that catalyses the hydrolysis of acetylcholine to choline. After several purification methods, 44.0 µg of acetylcholinesterase was purified from a crude extract and was found to catalyse the conversion of 16.0 μmol of acetylcholine (the substrate) to choline (the product) in 9 mins. What is the specific activity of acetylcholinesterase in units μmol min^-1 mg^-1.

(Round your answer to the nearest whole number. (i.e. If you calculated 40.03, input your answer as 40. Input only the numerical value. Do not input the unit).

Expert Solution

Step 1: Given data

Provided,

amount of acetylcholinesterase purified from the crude extract is 44.0 μg.
The amount of substrate (acetylcholine) converted by the enzyme is 16.0 μmol.
The time it took for this conversion to occur was 9 minutes.
