Verified step by step guidance

Step 1: Begin by understanding the role of enzymes in biological systems. Enzymes are specialized proteins that speed up chemical reactions without being consumed in the process.

Step 2: Eliminate incorrect options by analyzing their definitions. For example, 'genetic material' refers to DNA or RNA, which store genetic information, not proteins like enzymes.

Step 3: Consider the option 'structural components.' While some proteins serve structural roles (e.g., collagen), enzymes are not primarily structural; they function to catalyze reactions.

Step 4: Evaluate the option 'energy storage molecules.' Molecules like glycogen or lipids store energy, but enzymes do not serve this purpose.

Step 5: Conclude that enzymes act as 'biological catalysts,' which is the correct answer. They lower the activation energy of reactions, facilitating faster biochemical processes.
