Biological catalysts, known as enzymes, play a fundamental role in the body by speeding up chemical reactions. This acceleration is crucial because many biochemical reactions occur far too slowly at normal body temperatures without the assistance of enzymes. For example, the breakdown of food in digestion and the synthesis of DNA during cell replication are both facilitated by specific enzymes that lower the activation energy required for these processes. This capability allows the body to maintain vital functions efficiently and respond to changes in the internal and external environments promptly.

While detoxification, oxygen transport, and energy storage are important biological processes, they are not functions directly related to the role of biological catalysts. Detoxification processes may involve enzymes, but that is not their primary function in the context of being a biological catalyst. Similarly, oxygen transport is done by hemoglobin in red blood cells, and energy storage is managed by compounds like glycogen and fats, neither of which involve the catalytic action of enzymes. Instead, enzymes work primarily to facilitate and expedite various biochemical reactions necessary for life.
