Question

Select all of the answers that accurately describe enzymes.
A) Enzymes are two-dimenstional molecules.
B) Enzymes are generally composed of protein.
C) Enzymes are also called catalysts.
D) An enzyme can interact with many types of substrates.
E) The part of an enzyme that interacts with the substrate is known as the active site.

Accepted Answer

Enzymes are primarily composed of proteins, though some RNA molecules can also function as enzymes (ribozymes). They act as catalysts to speed up chemical reactions without being consumed in the process. The specific region of an enzyme where the substrate binds and the reaction is catalyzed is known as the active site.
