Verified step by step guidance

Understand the primary functions of proteins in biological systems. Proteins are versatile macromolecules that perform a wide range of functions, including acting as enzymes, structural components, signaling molecules, and transporters.

Eliminate incorrect options based on the known roles of proteins. Proteins are not primarily used for energy storage; carbohydrates and lipids serve this function. Proteins also do not store genetic information; this is the role of nucleic acids like DNA and RNA.

Focus on the correct function: catalyzing biochemical reactions as enzymes. Enzymes are specialized proteins that accelerate chemical reactions in biological systems by lowering the activation energy required for the reaction.

Consider the other incorrect option: forming the phospholipid bilayer of membranes. This is primarily the role of lipids, specifically phospholipids, not proteins.

Conclude that the primary function of proteins in this context is catalyzing biochemical reactions as enzymes, which is essential for maintaining life processes and metabolic pathways.
