Which of the following correctly pairs a biomolecule to its function?

Question

A.Carbohydrate: stores genetic information
B.Enzyme: increases the rate of a reaction
C.Lipid: makes the cell walls of plant cells
D.Nucleic acid: makes the cell membrane's phospholipid bilayer

Answer 1

The correct pairing from the options provided is:

B. Enzyme: increases the rate of a reaction

Here’s a brief explanation for each option:

A. Carbohydrate: stores genetic information - This is incorrect. Carbohydrates are primarily used for energy storage and structural purposes, not for storing genetic information. Nucleic acids (DNA and RNA) are responsible for storing genetic information.

B. Enzyme: increases the rate of a reaction - This is correct. Enzymes are catalysts that speed up chemical reactions by lowering the activation energy required.

C. Lipid: makes the cell walls of plant cells - This is incorrect. While lipids are important for cell membranes (such as phospholipids), plant cell walls are primarily made up of cellulose, which is a carbohydrate.

D. Nucleic acid: makes the cell membrane's phospholipid bilayer - This is incorrect. Nucleic acids (DNA and RNA) are involved in the storage and transmission of genetic information, but they do not form the phospholipid bilayer. Phospholipids, which are a type of lipid, form the bilayer.

Therefore, option B is the only correct pairing.
