Multiple Choice

Which of the following macromolecules contains nitrogen as a key component of its structure?

Proteins

Carbohydrates

Lipids

Nucleic acids

Verified step by step guidance

Identify the key elements that make up each type of macromolecule: Proteins, Carbohydrates, Lipids, and Nucleic acids.

Recall that proteins are composed of amino acids, which contain nitrogen in the form of an amino group \( \text{(-NH}_2) \).

Understand that carbohydrates are primarily composed of carbon, hydrogen, and oxygen, and do not typically contain nitrogen.

Recognize that lipids are also mainly composed of carbon, hydrogen, and oxygen, and generally lack nitrogen in their structure.

Remember that nucleic acids, such as DNA and RNA, contain nitrogenous bases, which include nitrogen as a key component of their structure.
