Quizplus · Accepted Answer

Proteins are large organic molecules that are made up of the elements C, H, O, N, and sometimes S. Nucleic acids are made up of these same elements but are not classified as large organic molecules like proteins. Polysaccharides are composed solely of carbon, hydrogen, and oxygen while true fats are composed of carbon, hydrogen, and oxygen, but not nitrogen or sulfur. Therefore, the best choice would be C) protein.
