The right answers are B, C and D.

An enzyme is a protein with catalytic properties. Virtually all biomolecules capable of catalyzing chemical reactions in cells are enzymes; some catalytic biomolecules, however, consist of RNA and are therefore distinct enzymes: they are ribozymes.

An enzyme acts by lowering the activation energy of a chemical reaction, which increases the rate of reaction.
