Question

biomolecules are essential for building cell structures. which of the following correctly matches a type of biomolecule with its primary function within the structure of a cell? a carbohydrates - store genetic information and direct cell activities. b lipids - form the main structure of the cell membrane and provide long - term energy storage. c proteins - mainly serve as a source of quick energy for the cell. d nucleic acids - make up the flexible framework of the cytoskeleton.

Explanation:

Carbohydrates are for quick - energy, nucleic acids store genetic information, and proteins are involved in many functions including being part of the cytoskeleton but not its main makeup. Lipids form the phospholipid bilayer of the cell membrane and are used for long - term energy storage.

Answer:

B. Lipids - Form the main structure of the cell membrane and provide long - term energy storage.
