All organic compounds are essential for life. Some compounds act as building blocks for muscle tissue and hair. Others are responsible for determining which traits are inherited by an organism. Which of the following combination of macromolecules provide energy for basic life functions?(1 point)
water and carbohydrates
[nucleic acids and proteinD]
lipids and carbohydrates
lipids and nucleic acids
lipids and carbohydrates
To determine which combination of macromolecules provide energy for basic life functions, we need to understand what macromolecules are and their role in providing energy.
Macromolecules are large, complex molecules made up of smaller subunits known as monomers. The main macromolecules in living organisms are carbohydrates, lipids, proteins, and nucleic acids.
Carbohydrates are the primary source of energy for the body. They are broken down into glucose, which can be readily used by cells for energy production.
Lipids, such as fats and oils, also serve as a significant energy source. They provide a more concentrated form of energy compared to carbohydrates and are especially important for long-term energy storage.
Proteins are not primarily used as an energy source but have other important functions in the body, such as building tissues, enzymes, and hormones. However, in certain circumstances, proteins can be broken down and used for energy.
Nucleic acids, like DNA and RNA, are not directly involved in providing energy for basic life functions. Instead, they are responsible for genetic information storage and transmission.
Based on this information, the correct combination of macromolecules that provide energy for basic life functions is:
Carbohydrates and lipids
Therefore, the correct answer is "lipids and carbohydrates."
