Question 10


  1. A hummingbird is “drinking” nectar containing sugar from a red columbine flower. Arrange the following events to occur in the hummingbird in order from the first to last:

    1. Glucose sugar is converted to pyruvate.
    2. Energy from high-energy electrons is released from an electron transport chain. This energy is used to make ATP.
    3. The hummingbird exhales carbon dioxide and energy is stored in electron carriers.
    4. The hummingbird has the ability to beat its wings 40 – 80 times a second.
    A.
    B.
    C.
    D.

    C.
    D.
    E.

Question 12

During the Calvin-Benson cycle (carbon-fixing reactions), in the red Columbine plant, high-energy electrons are transferred into a newly made 3-carbon compound. Eventually, these electrons will end up as part of glucose molecules. What was the original source of these electrons in photosynthesis?


  1. A.
    B.
    C.
    D.
    E.
