Question

an enzyme's active site is unique to the substrate that binds to it. what causes the unique conformation of the active site? an enzyme's active site is unique to the substrate that binds to it. what causes the unique conformation of the active site? secondary structure of the polypeptide caused by hydrogen bonds. primary structure of the protein caused by peptide bonds.

Answer 1

The unique conformation of an enzyme's active site is determined by the tertiary structure of the protein, which is formed through the folding and bending of the polypeptide chain or chains. The active site is a specific region within the enzyme where the substrate binds, and its shape and chemical environment are complementary to the structure of the substrate.

Step-by-step explanation:

The unique conformation of an enzyme's active site is caused by the tertiary structure of the protein, which is determined by the folding and bending of the polypeptide chain or chains when the protein acquires its tertiary structure. The active site is a small region within the enzyme where the substrate binds for the reaction. It is generally a specific pocket or crevice formed by the folding pattern of the protein. The amino acid residues within the active site create a very specific chemical environment that is complementary to the structure of the substrate, allowing for a specific binding.
