Stereospecificity may be explained by
A) the catalytic constant.

D) competitive inhibitors.
E) saturation.

Question

Quizplus · Accepted Answer

Stereospecificity refers to the ability of an enzyme to selectively bind and catalyze a specific stereoisomer of a substrate. This specificity is often due to the requirement of three-point attachment, where the enzyme has specific binding sites for the functional groups on the substrate that are arranged in a particular spatial orientation. Therefore, choice C, three point attachment, is the best explanation for stereospecificity.
