The key function of lipids in biological systems is that they make up cell membrane structure and provide long-term energy storage. Lipids, such as phospholipids, are essential components of cell membranes, which help maintain cellular integrity and regulate the movement of substances in and out of cells. Additionally, lipids serve as a major source of energy storage, particularly in the form of triglycerides.

ARE YOU SURE
Yes, I am sure. In biological systems, lipids indeed play crucial roles as structural components of cell membranes and as long-term energy storage.
-
Cell Membrane Structure: Phospholipids are the primary building blocks of cell membranes, forming a bilayer that provides a barrier to protect the cell and regulate the transport of substances.
-
Long-Term Energy Storage: Lipids, particularly triglycerides, store energy efficiently due to their high energy content. They are utilized by organisms for energy when needed, especially during prolonged periods without food.
The other options you mentioned do not accurately represent the functions of lipids:
- Quick energy is typically derived from carbohydrates.
- Carbohydrates are the primary building blocks of sugars and starches, not lipids.
- Nucleic acids are synthesized from nucleotides, which are not directly related to lipids.
Therefore, the initial statement about the functions of lipids is correct.
