Question

Identify the function of enzymes.

Enzymes are chemical substrates, which lower the activation energy of chemical processes by using their three-dimensional structure to capture reactants and hold them in a particular orientation that facilitates the reaction.

Enzymes are biological catalysts, which increase the activation energy of biological processes by using their three-dimensional structure to capture reactants and hold them in a particular orientation that facilitates the reaction.

Enzymes are biological catalysts, which lower the activation energy of biological processes by using their three-dimensional structure to capture reactants and hold them in a particular orientation that facilitates the reaction.

Answer 1

Enzymes are biological catalysts (they are not just simple chemical substrates. As they are made of long chains of amino acids in a particular sequence to facilitate a particular reaction) which lower the activation energy of biological processes (function of a catalyst is to facilitate a reaction which they do mostly by lowering the activation energy of the reaction) by using their three-dimensional structure to capture reactants and hold them in a particular orientation that facilitates the reaction.

Last statement about enzymes is correct.
