All of the following elements present in all carbohydrates except:
Correct answer: D. Nitrogen
- A. Carbon
- B. Hydrogen
- C. Oxygen
- D. Nitrogen
Explanation
Option D is correct. All of the following elements are present in all carbohydrates except nitrogen..Nitrogen is not a common element found in carbohydrates. Carbohydrates are organic compounds that are made up of carbon, hydrogen, and oxygen. They are the most abundant organic compounds in living organisms, and they play a variety of important roles, including energy storage, structure, and signaling. The basic unit of a carbohydrate is a sugar molecule. Sugar molecules can be linked together to form larger molecules, such as starch, cellulose, and glycogen.

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.
