In Considering the 'Active Site' of Enzymes, a Fair Generalization

question 13

Multiple Choice

In considering the 'active site' of enzymes, a fair generalization is that

• A) nearly all the amino acid side-chains of the protein must directly participate in catalysis.
• B) all the amino acid residues which are involved in the active site are adjacent because they are located on the same short stretch of the polypeptide backbone.
• C) the conformation of the active site region does not exist at all until the substrate is bound.
• D) the amino acid residues which form the active site are in close proximity because of the specific three-dimensional conformation the protein has adopted.
• E) only one amino acid residue is involved in the active site.
