How does the structure of this enzyme help with its function?
since the enzyme's shape matches the substrate's shape, it catalyzes only reverse reactions
the enzyme's shape complements the substrate's shape, so it only catalyzes specific reactions
the enzyme's active site is amorphous and can change its shape to fit any substrate
since the enzyme is larger than the substrate, catalytic reactions can occur within the enzyme itself
