The induced-fit model states that
A.the active site changes shape slightly as the substrate binds
B.the active site is completely rigid
C.substrates reshape the whole enzyme permanently
D.enzymes change into products
Explanation
Core Concept
Substrate binding molds the active site around it, optimizing catalysis. This refinement is why specificity and activity are both high.
Correct Answer
Athe active site changes shape slightly as the substrate binds
