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.
