Verified step by step guidance

Step 1: Begin by identifying the major functions of proteins in the human body. Proteins are versatile macromolecules that play critical roles in various biological processes, including catalysis, transport, structural support, and signaling.

Step 2: Analyze each option provided in the question. For example, 'Catalyzing biochemical reactions as enzymes' is a well-known function of proteins, as enzymes are specialized proteins that accelerate chemical reactions.

Step 3: Evaluate the option 'Transporting molecules across cell membranes.' Proteins such as transporters and channels facilitate the movement of molecules like ions and nutrients across membranes, making this a valid function.

Step 4: Consider the option 'Providing structural support to cells and tissues.' Structural proteins like collagen and keratin are essential for maintaining the integrity and shape of cells and tissues, confirming this as a major function.

Step 5: Examine the option 'Storing genetic information.' This is NOT a function of proteins. Genetic information is stored in nucleic acids, specifically DNA and RNA, not proteins. Proteins do not play a role in genetic information storage, making this the correct answer to the question.
