Multiple Choice

Which of the following statements describe(s) the characteristics of an enzyme active site that result in highly specific substrate selectivity and highly specific catalytic ability?

• A)The active site is a highly specific three-dimensional cleft or pocket formed from different parts of the primary amino acid sequence.
• B)The active site takes up only a small part of the total enzyme.
• C)Amino acid side chains at the active site combine to create a microenvironment where the arrangement of atoms is uniquely matched to characteristics of only a single substrate species.

• E)Some amino acids at the active site actively participate in making and breaking of bonds by lowering the activation energy of the overall reaction.
