Which of the following processes does the body NOT use proteins to perform?

• A. Transporting molecules across membranes
• B. Storing genetic information
• C. Providing structural support to cells
• D. Catalyzing biochemical reactions

Answer: (B)

Verified step by step guidance

1. Identify the primary functions of proteins in the body. Proteins are involved in various biological processes, such as transporting molecules across membranes, providing structural support to cells, and catalyzing biochemical reactions (acting as enzymes).
2. Understand the role of proteins in transporting molecules. Proteins like channel and carrier proteins are embedded in cell membranes and facilitate the movement of substances across the membrane.
3. Examine the structural role of proteins. Proteins such as collagen and keratin provide structural support to cells and tissues, maintaining their shape and integrity.
4. Analyze the catalytic role of proteins. Enzymes, which are specialized proteins, speed up biochemical reactions by lowering the activation energy required for the reactions to occur.
5. Recognize that storing genetic information is not a function of proteins. This role is performed by nucleic acids, such as DNA and RNA, which are responsible for storing and transmitting genetic information in living organisms.
