Quiz: Macromolecules

A biology student creates a table that shows the function of the four major macromolecules. For which macromolecule does the student list an incorrect function?

• The lipid because they are responsible for long-term energy storage.

• The proteins, because they are responsible for helping with chemical reactions within the organelles of the plant.

• The carbohydrates because they are responsible for the structure of the cell membrane.

• The nucleic acids because they are responsible for transmitting genetic information for the production of proteins within the cell.
