Why are organic molecules important to living things?

Answer 1

Organic molecules are important to living things because life is based on the properties of carbon.

Properties of Carbon

  • Carbon is an important element because it can form four covalent bonds.
  • Carbon skeletons can vary in length, branching, and ring structure.
  • The carbon skeletons contain the functional groups that are involved in biochemical reactions.

    Four types of organic molecules are important for life.

    Carbohydrates

    • Are made of sugar molecules.
    • Provide energy and structure.

      Lipids

      Lipids are a large class of hydrophobic organic molecules.

      • Fats are made of glycerol plus fatty acids; they serve as a backup source of energy.
      • Phospholipids contain polar and nonpolar groups; they form cellular membranes.
      • Steroids have a characteristic ring structure; they include cholesterol and various hormones.

        Nucleic acids

        • Consist of long chains of nucleotides.
        • Are the molecules of the genetic code.
        • Are also important as energy carriers.

          Proteins

          • Consist of long chains of amino acids.
          • Are necessary for growth and repair of tissues.
          • Are crucial to life and perform a wide range of functions.

Answer 2

Because they are the building blocks of life, organic molecules are vital to all living things. They are mainly made up of carbon atoms bound to elements like hydrogen, oxygen, nitrogen, and phosphorus. Organic molecules also form the basis of biological structures, such as proteins, carbohydrates, lipids, and nucleic acids. Organic molecules are necessary for a variety of cellular processes, including energy production, cell structure, growth, and reproduction. They also play critical roles in biochemical reactions, signal transduction, and the regulation of gene expression. In summary, organic molecules are essential to the survival and functionality of living organisms.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
