A complex aminoacid subunits is called?
Correct answer: C. Protein
- A. Lipids
- B. Carbohydrate
- C. Protein
- D. All of these
Explanation
Protein quaternary structure refers to the organization, number, and spatial arrangement of multiple folded protein subunits that assemble into a functional multi-subunit complex. This level of structure is crucial for the protein's biological activity, stability, and ability to interact with other molecules, as seen in hemoglobin, which consists of four subunits working together to transport oxygen efficiently.

About Biological Molecules
The chapter covers water's polarity and biological roles, carbohydrates, lipids, proteins and nucleic acids, including their monomers, bonds, structures and functions. It also distinguishes RNA from DNA and explains conjugated molecules such as glycoproteins, glycolipids and nucleoproteins, which combine organic molecules with a non-protein component.
