Question

Which category of organic molecules is correctly paired with one of its functions? A. carbohydrates – provides structural component of cell membrane B. lipids – transmits genetic information C. nucleic acids – provides cells with immediate energy D. proteins – speed up chemical reactions

Answer 1

The category of organic molecules that is correctly matched with one of its functions is (D) proteins – speed up chemical reactions.

Proteins are made up of amino acids and they serve a variety of cellular functions. These organic molecules also function as enzymes as well as hormones. Enzymes are proteins which act as biocatalysts and increase the rate of chemical reactions.

Carbohydrates are the macromolecules with the general formula (CH₂O)ₙ, where 'n' denotes the number of carbon atoms in the molecule. Their main function is to provide immediate energy to the body.

Lipids are non-polar organic molecules. They are hydrophobic in nature and are utilized for long-term energy storage by the cell. Nucleic acids are responsible for transmitting the genetic information from one generation to another.
