Question

which macromolecule is made up of carbon, hydrogen, and oxygen in a 1:2:1 ratio?
carbohydrates
lipids
proteins
nucleic acids

Explanation:

Carbohydrates are composed of carbon, hydrogen, and oxygen in a 1:2:1 ratio. For example, glucose (\(C_6H_{12}O_6\)) has 6 carbon atoms, 12 hydrogen atoms, and 6 oxygen atoms. The ratio of \(C:H:O = 6:12:6=1:2:1\). Proteins contain nitrogen in addition to carbon, hydrogen, and oxygen. Lipids have a different hydrogen - to - oxygen ratio compared to 2:1 (they have more hydrogen). Nucleic acids contain nitrogen and phosphorus in addition to carbon, hydrogen, and oxygen.

Carbohydrates
