Title and Description Guru

A model that explains how enzymes work without a substrate

An alternative to the lock and key model

A model that explains how substrates work without an enzyme

A modification to the lock and key model (correct)

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

Enzymes and substrates fit together perfectly like a lock and key

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

Enzymes and substrates interact without any shape changes

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

It is a rigid structure that perfectly fits the substrate

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

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