An enzyme changes shape when catalyzing a chemical reaction,leading to a(n)_____ fit.

Question

Quizplus · Accepted Answer

When an enzyme binds to its substrate, it induces a conformational change in the enzyme which results in a tighter fit between the enzyme and the substrate. This induced fit model explains how enzymes are able to catalyze reactions with such high specificity and efficiency. The other answer choices (perfect, partial, and tight) do not accurately describe the conformational change that occurs during enzyme-catalyzed reactions.
