What Proteins,DNA Fat and sugar have in common?
Airida [17]

Answer:

What proteins,DNA, fat and sugar have in common is that they are biomolecules, or organic molecules, which all contain carbon and are necessary for the vital functions of living beings.

Explanation:

The principal biomolecules of living beings are proteins, carbohydrates or sugars, lipids and nucleic acids, such as DNA. All these molecules contain carbon in their composition and have hydrocarbon structures that may also have oxygen, nitrogen, sulfur and phosphorus in their composition.

Each of these biomolecules has a specific function and is indispensable for the development of life:

  1. <em><u>Proteins</u></em><em>: they are composed of amino acids and participate in the constitution of tissues, metabolic processes and the regulation of organic functions. </em>
  2. <em><u>Carbohydrates</u></em><em>: they are the main energy substrate, participating in the metabolism that leads to obtaining ATP. </em>
  3. <em><u>Lipids</u></em><em>: they are the main constituent of cell membranes, as well as constituting other organic molecules and being a reserve energy source. </em>
  4. <em><u>Nucleic acids</u></em><em>: DNA and RNA participate in the process of storage and transmission of genetic information, being responsible for processes such as the synthesis of proteins and other molecules. </em>

<u>The characteristics that have in common proteins, DNA, lipids and carbohydrates are their carbon-based composition, being organic molecules and being essential for living beings</u>.
