Respuesta :
Macromolecules are an essential part of the diet and are required to perform several metabolic processes like respiration.
Which macromolecules can be used to yield energy?
- Carbohydrates are the primary source of energy in all living organisms. Carbohydrate such as glucose and starch is broken down to yield ATP.
- Proteins are not the primary source of energy and are broken down into ketone bodies to obtain energy in time of need. Triglycerides or lipids are also used to yield energy and they gave the maximum amount of energy when broken down.
- Nucleic Acids are the macromolecules found in DNA and viruses. These are used to encode information and not yield energy.
Thus, the nucleic acids are not used to yield energy.
