Answer
A) Store energy
Solution
The correct answer is:
A) Store energy
Explanation:
Lipids play several vital roles in living organisms, including:
-
Storing Energy: Lipids, particularly triglycerides, are excellent for energy storage. They can store more energy per gram than carbohydrates or proteins, making them efficient for long-term energy reserves.
-
Structural Components: Phospholipids and cholesterol are essential components of cell membranes, providing structural integrity and fluidity.
-
Insulation and Protection: Lipids help insulate the body and protect vital organs.
-
Signaling Molecules: Some lipids act as hormones and signaling molecules, influencing various physiological processes.
The other options are functions of different biomolecules:
-
B) Serve as the primary structural component of DNA: This is incorrect because DNA’s primary structural components are nucleotides, which consist of sugars, phosphates, and nitrogenous bases, not lipids.
-
C) Transport oxygen: This is a function of hemoglobin, a protein found in red blood cells.
-
D) Break down proteins: Protein digestion is carried out by enzymes like proteases, which are themselves proteins.
Therefore, option A accurately describes a function of lipids.

Lipids are like the body’s trusty storage vaults, primarily known for their role in storing energy. They are packed with calories and provide more than double the energy per gram compared to carbohydrates or proteins. Beyond energy, they also help in forming cell membranes, making them essential for keeping things organized and functional in the body’s cellular world!
In practical terms, lipids also play a critical role in maintaining body temperature and supporting cell signaling processes. Think of them as the body’s insulated blankets, helping to preserve heat and ensure that communication between cells happens smoothly. Plus, they assist in the absorption of fat-soluble vitamins like A, D, E, and K, which are crucial for various bodily functions!
