Title and Description Guru

A modification to the lock and key model (correct)

A model that explains how substrates work without an enzyme

A model that explains how enzymes work without a substrate

An alternative to the lock and key model

Enzymes change shape to fit the substrate, facilitating the chemical reaction (correct)

Substrates change shape to fit the enzyme, facilitating the chemical reaction

Enzymes and substrates fit together perfectly like a lock and key

Enzymes and substrates interact without any shape changes

It is a rigid structure that perfectly fits the substrate

It is a structure that is not involved in the chemical reaction

It is a flexible structure that continuously reshapes as the substrate interacts with the enzyme (correct)

It is a structure that only binds to the substrate but does not change shape
