For which macromolecule does the student list an incorrect function?
MACROMOLECULE
- lipids
- proteins
- nucleic acids
- carbohydrates
FUNCTION
- transport oxygen in the blood.
- help with muscle contractions.
- store and transmit genetic information.
- provide usable chemical energy for cells.
A: the lipids, because they are responsible for long-term energy storage
B. the carbohydrates, because they are entirely responsible for the structure of the cell membrane
C. the proteins, because they are responsible for helping plants retain water
D. the nucleic acids, because they are responsible for providing support for the cell wall
1 answer
The correct answer is: D. the nucleic acids, because they are responsible for providing support for the cell wall.
Nucleic acids (like DNA and RNA) primarily function in storing and transmitting genetic information, not in providing structural support for the cell wall. This function is more closely associated with carbohydrates (such as cellulose in plants) and other structural proteins.
