Verified step by step guidance

Understand the definition of enzymes: Enzymes are specialized proteins that act as biological catalysts, meaning they speed up chemical reactions without being consumed in the process.

Eliminate incorrect options: Review the provided choices and identify which ones do not align with the definition of enzymes. For example, enzymes are not genetic material carriers (DNA and RNA fulfill this role) or primary energy storage molecules (such as carbohydrates and lipids).

Focus on the correct role of enzymes: Enzymes facilitate biochemical reactions by lowering the activation energy required for the reaction to occur, making processes in living organisms more efficient.

Consider structural components: While enzymes are proteins, they are not structural components of cell membranes. Structural components include phospholipids and membrane proteins, which serve different functions.

Select the correct answer: Based on the analysis, the correct answer is 'biological catalysts that speed up chemical reactions,' as this accurately describes the primary function of enzymes in biochemistry.
