Select all that apply. enzymes are not required to sustain the life of an organism act as catalysts in chemical reactions of cells interact with specific substrates like a lock and key can lower the required activation energy for reactions in living organisms

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.
