Q. For an enzyme assay, it was observed based on the change of the product thus formed that 100 μ moles of the substrate is converted to product per minute per milligram of the enzyme used. The specific activity of the enzyme would be

A) 100 units
B) 1 units
C) 1000 units
D) 10 units

... Answer is A). 100 units

Specific activity in biochemistry is defined as the amount of product formed by an enzyme in a given amount of time. Specific activity is often reported in units (U) per mg of enzyme, where 1 unit is equal to 1 kg mol of product formed per minute.
