Question

biomolecules are macromolecules that perform specialized functions within cells. analyze the diagram. which of the following describes the biological macromolecule and its function? carbohydrates: help grow and repair tissue lipids: improves flexibility of the cell membrane proteins: carries the genetic code nucleic acid: used as the primary source of energy

Explanation:

Carbohydrates are the primary energy - source, not for tissue growth and repair. Proteins are for growth and repair. Proteins do not carry the genetic code; nucleic acids do. Nucleic acids are not the primary energy source. Lipids, such as phospholipids, contribute to the flexibility of the cell membrane.

Answer:

B. Lipids: improves flexibility of the cell membrane
