    chlorophyll
  • Question 7
    20 seconds
    Q. Autotroph or heterotroph?
    answer choices
    Autotroph
    Heterotroph
  • Question 8
    20 seconds
    Q. Autotroph or heterotroph?
    answer choices
    Autotroph
    Heterotroph
  • Question 9
    60 seconds
    Q. Which of the following is the correct equation for PHOTOSYNTHESIS?
    answer choices
    6CO2 + 6H2O --> 6O+ C6H12O6
    6CO+ C6H12O6 + 6H2O --> O
    6O2 + 6H2O --> 6CO+ C6H12O6
    C6H12O6 + 6O2 ---> 6H2O + 6CO2

    answer choices
    They absorb light
    They power the light-dependent reactions
    They are light-reflecting pigments
    They act as short-term energy storage
  • Question 12
    60 seconds
    Q. Use the diagram to answer the question. Between which parts of the molecule must the bonds be broken to form an ADP molecule?
    answer choices
    A and B
    A and C

    C and D
  • Question 13
    60 seconds
    Q. Is ADP or ATP more like a fully charged battery, and why?
    answer choices
    ADP, because it has three phosphate groups; breaking and reforming the bonds among them releases energy.
    ATP, because it has three phosphate groups; breaking and reforming the bonds among them releases energy.
    ADP, because it has two phosphate groups; breaking and reforming the bonds among them releases energy.
    ATP, because it has two phosphate groups; breaking and reforming the bonds among them releases energy.

    Heterotrophs obtain food from consuming other living or once-living things.
    Heterotrophs obtain food through the process of photosynthesis.
