Chapter 7: Self-Quiz

  1. Photosynthesis, which is measured in the leaf of a green plant exposed to different wavelengths of light, is
    1. highest in green light
    2. highest in red light
    3. highest in blue light
    4. highest in red and blue light
    5. the same at all wavelengths

  2. Where do the light-dependent reactions of photosynthesis occur?
    1. in the guard cells of the stomata
    2. in the chloroplast stroma
    3. within the thylakoid membranes of the chloroplast
    4. in the leaf cell cytoplasm
    5. in leaf cell mitochondria

  3. The oxygen produced during photosynthesis comes from
    1. the breakdown of CO2
    2. the breakdown of H2O
    3. the breakdown of both CO2 and H2O
    4. the breakdown of oxaloacetic acid
    5. photorespiration

  4. The role of accessory pigments is to
    1. provide an additional photosystem to generate more ATP
    2. allow photosynthesis to occur in the dark
    3. prevent photophosphorylation
    4. donate electrons to chlorophyll reaction centers
    5. capture additional light energy and transfer it to the chlorophyll reaction centers

  5. The generation of ATP by electron transport in photosynthesis and cellular respiration depends upon
    1. a hydrogen ion gradient across a membrane
    2. proton pumps driven by electron transport chains
    3. an ATP-synthesizing enzyme complex
    4. a, b, and c are all required for ATP generation.
    5. None of the above are required for ATP generation.

  6. Where do the light-independent, carbon-fixing reactions occur?
    1. in the guard cell cytoplasm
    2. in the chloroplast stroma
    3. within the thylakoid membranes
    4. at night in the thylakoids
    5. in mitochondria
