    Which statement best describes the function of a cell?

    • Large organic food molecules like protein must be initially broken down. Once the broken down nutrient enters the cell, the cell will use the building blocks to synthesize organic compounds necessary for life.

    • Large organic food molecules like protein directly enter the cell where they are used for energy.

    • Large organic food molecules like protein are broken down only after they enter the cell. Once broken down, the cell will excrete the broken down substances.

    • The cell makes its own protein and does not need nutrients from the outside environments.

    • The function of the cell is to convert proteins to amino acids.

    Correct Answer
    A. Large organic food molecules like protein must be initially broken down. Once the broken down nutrient enters the cell, the cell will use the building blocks to synthesize organic compounds necessary for life.
    Explanation
    This answer accurately describes the function of a cell. It states that large organic food molecules like protein need to be broken down before they can enter the cell.

    The cell structure responsible for controlling which molecules enter and leave the cell and for the recognition of chemical signals is the:

    • Cell wall

    • Nuclear membrane

    • Mitochondria

    • Chloroplast

    • Plasma membrane

    Correct Answer
    A. Plasma membrane
    Explanation
    The plasma membrane is responsible for controlling which molecules enter and leave the cell and for the recognition of chemical signals. It acts as a selectively permeable barrier, allowing certain molecules to pass through while preventing others from entering or leaving the cell. The plasma membrane also contains receptors that can recognize and bind to specific chemical signals, allowing the cell to respond to its environment. Unlike the other options listed, the plasma membrane is directly involved in regulating the movement of molecules in and out of the cell.

    Which statement best describes ATP:

    • When ADP is converted to ATP, energy is released when bonds are formed.

    • When ATP is converted to ADP and phosphate, energy is released from the bonds that break.

    • ATP is a reactant of photosynthesis.

    • ATP is a reactant of cellular respiration.

    • ATP is a product in the hydrolysis of ADP.

    Correct Answer
    A. When ATP is converted to ADP and phosphate, energy is released from the bonds that break.
    Explanation
    When ATP is converted to ADP and phosphate, energy is released from the bonds that break. This is because ATP is a high-energy molecule that stores energy in its phosphate bonds. When one of the phosphate groups is removed, ATP is converted to ADP (adenosine diphosphate), and the released phosphate group carries energy that can be used by the cell for various processes. This conversion of ATP to ADP is a key step in cellular energy metabolism.
