Tertiary Structure Specific Shape Active Site Maltase Essential

The tertiary structure of maltase is vital as it dictates the precise shape of the active site, which must be complementary to its substrate, maltose, for catalysis to occur.

The tertiary structure of maltase is crucial because it defines the specific shape of the active site, ensuring complementarity only to its substrate, maltose. Any alteration would prevent substrate binding and catalysis.

Front Why is the tertiary structure of maltase essential to its function? (3 marks)
Back Tertiary structure determines the
specific shape of the active site
The active site is only complementary to a
specific substrate
any change in shape will mean the
enzyme cannot catalyse that reaction
