Multiple Choice

Which of the following is NOT a function of lipids in the human body?

Storing genetic information

Acting as an energy reserve

Providing insulation and protection for organs

Verified step by step guidance

Step 1: Begin by understanding the functions of lipids in the human body. Lipids are a diverse group of molecules that play critical roles, including serving as structural components of cell membranes, acting as energy reserves, and providing insulation and protection for organs.

Step 2: Analyze each option provided in the question. For example, 'Serving as a major component of cell membranes' is a well-known function of lipids, specifically phospholipids, which form the bilayer structure of membranes.

Step 3: Evaluate the option 'Acting as an energy reserve.' Lipids, particularly triglycerides, are stored in adipose tissue and serve as a long-term energy source for the body.

Step 4: Consider the option 'Providing insulation and protection for organs.' Lipids, such as subcutaneous fat, help insulate the body and cushion organs from physical impact.

Step 5: Examine the option 'Storing genetic information.' This is not a function of lipids. Genetic information is stored in nucleic acids (DNA and RNA), not lipids. Therefore, this option is the correct answer to the question.
