Question

Quizplus · Accepted Answer

An enzyme's specificity for its substrate is due to the shape of its active site. The active site is complementary to the shape and chemical properties of the substrate, allowing for a specific and precise interaction. This is often described as a "lock-and-key" model, where the active site is the lock and the substrate is the key that fits into it. Changes in the shape of the active site, such as denaturation, can lead to a loss of specificity and a decrease in enzyme activity. Cofactors and coenzymes can also play a role in enzyme activity, but they do not determine the specificity of the enzyme for its substrate.
