<reasoning>

Analyze the role of enzymes in cellular activities

Cellular activities consist of metabolic chemical reactions that must occur rapidly to sustain life. Enzymes act as biological catalysts that speed up these biochemical reactions by lowering the activation energy required.

Evaluate the alternative options

Carbohydrates, polysaccharides, and lipids primarily serve as energy storage molecules, structural components, or signaling molecules, rather than direct regulators or catalysts of metabolic processes.
