What is the function of enzymes?

Enzymes are biological catalysts that play a crucial role in accelerating chemical reactions in living organisms. They work by lowering the activation energy required for a chemical reaction to proceed, which results in an increased rate of reaction. This is essential for cellular processes since many biochemical reactions occur too slowly at physiological temperatures without the assistance of enzymes. By facilitating these reactions, enzymes allow organisms to efficiently carry out metabolic processes needed for survival.

In contrast, the other options do not accurately describe the primary role of enzymes. While they might involve energy or temperature in their contexts, they do not encompass the catalytic function of enzymes in biological systems.
