Organic Compounds Quiz: Gilroy - Quiz


Questions and Answers
  • 1. 

    Water is an organic molecule.

    • A.

      True

    • B.

      False

    Correct Answer
    B. False
    Explanation
    Water does not contain carbon and therefore is not considered organic.

    Rate this question:

  • 2. 

    Organic Molecules exist as monomers and polymers.

    • A.

      True

    • B.

      False

    Correct Answer
    A. True
    Explanation
    Organic molecules can exist in two forms: monomers and polymers. Monomers are single units of organic molecules, while polymers are made up of multiple monomers bonded together. This statement is true because organic molecules can exist as both monomers and polymers, depending on their structure and function.

  • 3. 

    Carbon is the primary component of living things because it can form 2 bonds.

    • A.

      True

    • B.

      False

    Correct Answer
    B. False
    Explanation
    Carbon is the primary component of living things because it can form 2 bonds. This statement is false. Carbon is the primary component of living things because it can form 4 bonds. This property allows carbon to form large, complex molecules such as proteins, carbohydrates, and nucleic acids, which are essential for life.

    Rate this question:

  • 4. 

    Carbohydrates contain Carbon, Hydrogen, and Oxygen in a 1:3:1 ratio.

    • A.

      True

    • B.

      False

    Correct Answer
    B. False
    Explanation
    Carbohydrates do contain carbon, hydrogen, and oxygen, but not in a 1:3:1 ratio. The correct ratio is 1:2:1, meaning that for every carbon atom, there are two hydrogen atoms and one oxygen atom. Therefore, the statement is false.

    Rate this question:

  • 5. 

    Which of the following elements are found in lipids?

    • A.

      Carbon

    • B.

      Nitrogen

    • C.

      Sulfur

    • D.

      Phosphorus

    Correct Answer
    A. Carbon
    Explanation
    Lipids are organic compounds that are primarily composed of carbon, hydrogen, and oxygen atoms. Carbon is a key element found in lipids, as it forms the backbone of their structure. Lipids do not typically contain phosphorus, nitrogen, or sulfur, so these elements are not found in lipids.

    Rate this question:

  • 6. 

    Which of the following organic molecules are classified as monomers?

    • A.

      Starch

    • B.

      Protein

    • C.

      Amino Acid

    • D.

      Fat

    Correct Answer
    C. Amino Acid
    Explanation
    Amino acids are classified as monomers because they are the building blocks of proteins. Monomers are small molecules that can join together to form larger molecules called polymers. In the case of proteins, amino acids are linked together through peptide bonds to form long chains. Starch, on the other hand, is a polymer made up of many glucose monomers. Proteins and fats are not classified as monomers because they are already in their polymer forms.

    Rate this question:

  • 7. 

    Which of the following organic molecules are classified as polymers?

    • A.

      Monosaccharide

    • B.

      Fatty Acid

    • C.

      Polysaccharide

    • D.

      Nucleic Acid

    Correct Answer
    C. Polysaccharide
    Explanation
    Polysaccharides are classified as polymers because they are composed of repeating units of monosaccharides. Monosaccharides, on the other hand, are simple sugars and not polymers. Fatty acids are not polymers either, as they are single molecules and not composed of repeating units. Nucleic acids, such as DNA and RNA, can be considered polymers because they are made up of repeating nucleotide units. However, in this question, the correct answer is specifically polysaccharide as it is the only option that is exclusively classified as a polymer.

    Rate this question:

  • 8. 

    Which is NOT a function of proteins?

    • A.

      They both allow for heredity

    • B.

      They are both enzymatic

    • C.

      They both produce receptors

    • D.

      They both provide structure

    Correct Answer
    A. They both allow for heredity
    Explanation
    Proteins do not allow for heredity. Heredity is the passing of genetic information from one generation to the next, which is primarily carried out by nucleic acids like DNA and RNA. Proteins, on the other hand, have various functions in the body including enzymatic activity, receptor production, and providing structure to cells and tissues. However, they do not play a direct role in transmitting genetic information.

    Rate this question:

  • 9. 

    What is the function of proteins?

    • A.

      They provide structure of living things

    • B.

      They make up cell membranes

    • C.

      They make up cell walls

    • D.

      They allow for heredity

    Correct Answer
    A. They provide structure of living things
    Explanation
    Proteins play a crucial role in providing structure to living organisms. They are involved in forming the structural components of cells, tissues, and organs, such as muscles, skin, and bones. Proteins also contribute to the structural integrity of cell membranes, which control the movement of substances in and out of cells. While proteins are not directly responsible for making up cell walls, they do contribute to the strength and support of cell walls in certain organisms. However, proteins do not play a direct role in heredity, which is primarily governed by DNA and genes.
