The enzyme fumarase catalyzes the reversible hydration of fumaric acid to l-malate, but it will not catalyze the hydration of maleic acid, the cis isomer of fumaric acid. This is an example of: A. biological activity. B. chiral activity. C. racemization. D. stereoisomerization. E. stereospecificity.

Correct answer is e ( stereospecificity) .
The enzyme fumarase catalyzes the reversible hydration of fumaric acid to l-malate, but it will not catalyze the hydration of maleic acid, the cis isomer of fumaric acid. This is an example of stereospecificity .
Stereospecific: A reaction in which the stereochemistry of the reactants controls the outcome of the reaction. In general, one stereoisomer of certain reactant produces one stereoisomer of a certain product, whereas a different stereoisomer of the same reactant produces a different stereoisomer of the same product.
stereospecific mechanism specifies the stereochemical outcome of a given reactant,
