Q: A researcher develops an enzyme inhibitor by creating an analog that is very similar to the substrate of the enzyme. However, she finds that the inhibitor lacks some important similarities to the substrate and although the structures are substantially similar, the inhibitor does not bind to the enzyme. This observation suggests what about the nature of how the enzyme binds to its substrate?
A		The substrate forms covalent bonds to its enzyme
B		The inhibitor binds allosterically to the enzyme
C		The enzyme binds to its substrate using the induced fit model
D		The enzyme has very low affinity for its substrate
