Question

2.20 unit 2: biochemistry summative test
lipids perfom which of the following functions: (select all that apply)
□ long term energy storage
□ insulation from the cold
□ make up cell membranes
□ genetic code for traits

Explanation:

Lipids are a diverse group of organic compounds. Triglycerides (a type of lipid) are used for long - term energy storage. Fats (a lipid category) can act as insulation (e.g., in animals like whales, the blubber which is rich in lipids provides insulation from cold water). Phospholipids (a lipid type) are a major component of cell membranes, forming a bilayer. However, the genetic code for traits is carried by nucleic acids (such as DNA and RNA), not lipids.

Answer:

long term energy storage, insulation from the cold, make up cell membranes
