Perguntas do quiz (10)

  1. 1The water necessary for photosynthesis
    1. Ais split into H2 and O2
    2. Bis directly involved in the synthesis of carbohydrates
    3. Cprovides the electrons to replace the lost electrons in photosystem II
    4. DProvides the H+ needed to synthesize G3P
    5. Edoes none of the above
  2. 2In PSII, p680 differs from the other pigment molecules in the light-harvesting complex in that it
    1. Ais a carotenoid
    2. Babsorbs light energy and transfers that energy to other molecules with out the transfer of electrons
    3. Ctransfers an excited electron to the primary electron acceptor
    4. Ddoes not transfer an excited electron to the primary electron acceptor
    5. Eacts as an ATP synthase to produce ATP
  3. 3The cyclic electron flow that occurs via photosystem I produces
    1. ANADPH
    2. Boxygen
    3. CATP
    4. Dall of the above
    5. Ea and c only
  4. 4During linear electron flow, the high-energy electron from p680
    1. Aeventually moves to NADP+
    2. Bbecomes incorporated in water molecules
    3. Cis pumped into the thylakoid space to drive ATP production
    4. Dprovides the energy necessary to split water molecules
    5. Efalls back to the low-energy state in photosystem II
  5. 5During the first phase of the Calvin Cycle, carbon dioxide is incorporated into ribulose biphosphate (RuBP) by
    1. Aoxaloacetate
    2. Brubisco
    3. CRuBP
    4. Dquinone
    5. EG3P
  6. 6The NADPH produced during the light reactions is necessary for
    1. Athe carbon fixation phase, which incorporates carbon dioxide into an organic molecule of the Calvin Cycle
    2. Bthe reduction phase, which produces carbohydrates in the calvin cycle
    3. Cthe regeneration of RuBP of the Calvin Cycle
    4. Dall of the above
    5. Ea and b only
  7. 7The majority of the G3P produced during the reduction and carbohydrate production phase is used to produce
    1. Aglucose
    2. BATP
    3. CRuBP to continue the cycle
    4. DRubisco
    5. Eall of the above
  8. 8Photorespiration
    1. Ais the process where plant use sunlight to make ATP
    2. Bis an inefficient way plants can produce organic molecules and in the process use O2 and release CO2
    3. Cis a process that plants use to convert light energy to NADPH
    4. Doccurs in the thylakoid lumen
    5. Eis the normal process of carbohydrate production in cool, moist environments.
  9. 9Photorespiration is avoided in C4 plants because
    1. Athese plants separate the formation of a four-carbon molecule from the rest of the Calvin cycle in different cells.
    2. Bthese plants carry out only anaerobic respiration.
    3. Cthe enzyme PEP caroboxylase functions to maintain high CO2 concentrations in the bundle-sheath cells
    4. Dall of the above
    5. Ea and c only
  10. 10Plants commonly found in hot and dry environments that carry out carbon fixation at night are
    1. Aoak trees
    2. BC3 plants
    3. CCAM plants
    4. Dall of the above
    5. Ea and b only
