  • 2. 

    A_______ is a polymer constructed from a set of just 20 kinds of monomers called Amino Acids?

    Explanation
    A protein is a polymer constructed from a set of just 20 kinds of monomers called amino acids. Proteins play a crucial role in various biological processes and are essential for the structure, function, and regulation of cells and tissues. They are involved in tasks such as catalyzing chemical reactions, transporting molecules, providing structural support, and transmitting signals. The specific sequence and arrangement of amino acids in a protein determine its unique structure and function.

    What determines a Proteins function?

    • Shape

    • Taste

    • Reactivity

    • Number of electrons

    • Number of Protein

    Correct Answer
    A. Shape
    Explanation
    The shape of a protein determines its function. Proteins are made up of long chains of amino acids that fold into specific shapes. These shapes are crucial for the protein to interact with other molecules and carry out its specific function in the body. Different shapes allow proteins to bind to specific molecules, catalyze chemical reactions, or transport substances across cell membranes. Therefore, the shape of a protein is a key factor in determining its function.

    Rate this question:

  • 4. 

    Which of these is NOT a function of Protein

    • Defend Body from harmful microorganisms

    • Form hair

    • Form Muscle

    • Eat acids

    • Nutrient storage

    Correct Answer
    A. Eat acids
    Explanation
    Protein does not have the function of "eating acids". Proteins are essential macromolecules that perform various functions in the body, including defending the body from harmful microorganisms, forming hair, forming muscles, and acting as nutrient storage. However, "eating acids" is not a recognized function of proteins.

    Rate this question:

  • 5. 

    Proteins are made up of smaller units called __________ acids.

    Correct Answer
    amino acids, Amino Acids, Amino acids, Amino, amino
    Explanation
    Proteins are composed of smaller building blocks known as amino acids. These amino acids link together in long chains to form proteins, which are essential for numerous biological functions such as repairing tissues, making enzymes, and supporting immune responses. There are 20 different amino acids that combine in various sequences to create the thousands of proteins found in the human body.

    Rate this question:

  • 6. 

    ___________ is the chain of amino acids linked together by cells to create protein.

    Correct Answer
    Polypeptide
    Explanation
    A polypeptide is a chain of amino acids that are linked together by cells to form a protein. Proteins are essential for various biological functions and are made up of one or more polypeptide chains. These chains are formed through a process called protein synthesis, where cells link amino acids together in a specific sequence dictated by the genetic code. The resulting polypeptide chain then folds into a specific three-dimensional structure, which determines the protein's function in the body. Therefore, polypeptides are the building blocks of proteins.

    Rate this question:

  • 7. 

    Explain how heat can destroy a Protein.

  • 8. 

    How many amino Acids are there?

  • 9. 

    What determines the 3-D shape of a protein molecule?

  • 10. 

    When a protein loses its shape it also loses what?
