Question

unit 2.1 quiz- due 10/21
in addition to carbon, which elements are found in all biological macromolecules?
o nitrogen and oxygen
o hydrogen and nitrogen
o calcium and oxygen
o hydrogen and oxygen

Explanation:

Biological macromolecules include carbohydrates, lipids, proteins, and nucleic acids. Carbon (C), hydrogen (H), and oxygen (O) are present in all of these macromolecules. Nitrogen (N) is in proteins and nucleic acids but not in all (e.g., not in pure carbohydrates like glucose - \(C_6H_{12}O_6\)). Calcium (Ca) is not a component of the basic structure of these macromolecules.

Answer:

hydrogen and oxygen
