Why are Enzymes Considered Important Biological Catalysts

Question

Why are enzymes considered important biological catalysts?
A) Enzymes lower the entropy of a biochemical reaction.
B) Enzymes decrease the enthalpy of a biochemical reaction.
C) Enzymes increase the free energy of a biochemical reaction.
D) Enzymes supply the energy to initiate a biochemical reaction.
E) Enzymes lower the activation energy of a biochemical reaction.

Accepted Answer

Enzymes are considered important biological catalysts because they lower the activation energy required for a biochemical reaction to occur, making the reaction proceed more quickly and efficiently without being consumed in the process.
