Trivia Questions On Macromolecules! Quiz - Quiz


What do you know about macromolecules? Do you feel you can take on this quiz? It is a vast molecule, such as protein, normally constituted of the polymerization of lesser subunits known as monomers. They are, on average, composed of thousands of atoms or more. All life is composed of four building blocks, including carbohydrates, lipids, proteins, and nucleic acids. Take this quiz and learn more about macromolecules.


Questions and Answers
  • 1. 

    __________________ is a compound composed of hydrogen and oxygen.

    Explanation
    Water is a compound composed of hydrogen and oxygen. It is formed by the chemical bonding of two hydrogen atoms and one oxygen atom. The molecular formula for water is H2O, indicating that it contains two hydrogen atoms and one oxygen atom. Water is a vital substance for all living organisms and is commonly found in its liquid state on Earth's surface. It is also present in the form of ice (solid) and water vapor (gas).

    _____________________ is the attractive force between unlike substances.

    Explanation
    Adhesive strength refers to the attractive force between unlike substances. This force allows different materials to stick together, such as when glue adheres to paper or tape sticks to a surface. Adhesive strength is crucial in various applications, including construction, manufacturing, and everyday use. It ensures that materials can bond effectively and withstand forces like tension and shear.

    __________________ is the attraction of like molecules to each other. (stickiness)

    Explanation
    Cohesive strength refers to the ability of like molecules to attract and stick to each other. It is the force that holds similar molecules together, creating a cohesive bond. This attraction between like molecules is what gives substances their stickiness.

    ________________  js the reaction of a liquid surface with a solid; is allows water to creap up the interier of a narrow vessel.

    Explanation
    Capillarity refers to the phenomenon where a liquid surface reacts with a solid, allowing the liquid to creep up the interior of a narrow vessel. This is possible due to the cohesive forces between the liquid molecules and the adhesive forces between the liquid and the solid surface. These forces cause the liquid to rise against gravity, creating a concave meniscus in a narrow tube. This phenomenon is commonly observed in capillary tubes, plants, and other porous materials.

    A compound that is derived from living things and contains carbon.

    • A.

      Organic Compounds

    • B.

      Non-Organic Compunds

    • C.

      Analysis

    • D.

      Experimental

    • E.

      None of the above.

    Correct Answer
    A. Organic Compounds
    Explanation
    Organic compounds are derived from living things and contain carbon. This means that they are composed of carbon atoms bonded together with other elements such as hydrogen, oxygen, nitrogen, and sulfur. Examples of organic compounds include carbohydrates, proteins, lipids, and nucleic acids. Non-organic compounds, on the other hand, do not contain carbon and are typically derived from minerals or inorganic sources. Analysis and experimental are not relevant to the definition of organic compounds, and therefore, the correct answer is "Organic Compounds".

    An organic compound present in the cells of all living things and a major organic nutrient for humans is a ___________________.

    Correct Answer
    carbohydrate
    Explanation
    Carbohydrates are organic compounds that are present in the cells of all living things and are a major source of energy for humans. They consist of carbon, hydrogen, and oxygen atoms and are found in various forms such as sugars, starches, and fibers. Carbohydrates play a crucial role in providing energy for cellular processes and are essential for the proper functioning of the body.

    Which of the following is an organic molecule, DNA or RNA, that stores and carries important information for cell function.

    • A.

      Chromosome

    • B.

      Nucleic Acids

    • C.

      Peptopie Acid

    • D.

      Organic Acid

    • E.

      None of the above.

    Correct Answer
    B. Nucleic Acids
    Explanation
    Nucleic Acids are organic molecules that store and carry important information for cell function. They are present in both DNA and RNA, which are the two types of nucleic acids found in cells. DNA stores genetic information and carries instructions for the synthesis of proteins, while RNA plays a crucial role in protein synthesis. Therefore, nucleic acids are the correct answer as they are the organic molecules responsible for storing and carrying important information in cells.

    __________________ is the heredity information in the form of a large molecule call deoxyribonucleic acid.

    Correct Answer
    DNA
    dna
    D.N.A
    d.n.a
    Explanation
    The heredity information in the form of a large molecule is called deoxyribonucleic acid (DNA). It can be represented in various ways, such as DNA, dna, D.N.A, or d.n.a.

  • 9. 

    A _____________________ is a kind of organic compound that is soluble in water, such as fats and steroids.

    Correct Answer
    lipid
    Explanation
    A lipid is a type of organic compound that is soluble in water, such as fats and steroids. Lipids are hydrophobic molecules that play a crucial role in various biological processes. They are an essential component of cell membranes, providing structure and regulating the flow of molecules in and out of the cell. Lipids also act as a source of energy, insulation, and protection for organs. Due to their hydrophobic nature, lipids do not dissolve in water but can be dissolved in organic solvents.
