What is the primary function of enzymes in metabolism?

The primary function of enzymes in metabolism is to facilitate most reactions involved in the metabolic processes. Enzymes act as biological catalysts that speed up chemical reactions by lowering the activation energy required for those reactions to occur. This acceleration is crucial because many metabolic reactions would occur too slowly at normal body temperatures to sustain life.

Enzymes are highly specific, meaning each enzyme typically catalyzes a specific reaction or set of reactions. They ensure that metabolic pathways operate efficiently and in coordination with one another, allowing the organism to derive energy from nutrients, synthesize essential molecules, and maintain overall homeostasis.

While other functions or processes mentioned in the choices, such as storing genetic information or transporting molecules, are crucial within biological systems, they do not directly involve the primary role of enzymes in metabolism. Enzymes primarily focus on facilitating and regulating the myriad chemical reactions that underpin metabolic activity, making option B the correct answer.
