Question

2 of 6 7. Compare photosynthesis with cellular respiration, place agree or disagree beside the answer below Photosynthesis Cellular respiration No CO, is reduced in this C,HzO, becomes oxidized in this process. Overall, this process is exergonic. Overall, this process is No Yes Yes No 8. The Calvin cyele is also referred to as the light-independent reactions, Briefly explain why referring to the chemical reactions of the Calvin cycle as the light-independent reactions is only partially accurate. 9. A toxin is found to inhibit the uptake of CO, into plant leaves. This toxin would most directly affect the a. light reactions b. splitting of H,O c. Calvin cycle d. absorption of solar energy The light reactions: Converting solar energy to chemical energy 1. True or false: Red wavelengths of light have more energy than purple wavelengths of light. If false, make it a correct statement. Refer to Figure 7.6A on page 112 in your textbook for help to answer this question 2. A botanist discovers a new plant species in the Amazon rainforest that has blue leaves, Briefly explain what can be inferred about the pigments in the leaves of this plant

Explanation / Answer

7. The give table for comparison between photosynthesis and cellular respiration is true. I am agree with the table.

8. None of the steps in the Calvin Cycle may require light directly but the reaction usually occurs in daylight because it depends on the products from light reactions which are light-dependent.Although the chemical reactions of the Calvin cycle do not directly depend on solar energy, the reactions do depend on the products produced by the light reactions.

9. The Option (c) is correct. A toxin is found to inhibit the uptake of CO2 into plant leaves.This toxin would most directly affect the Calvin cycle.

The light reactions: Converting solar energy to chemical energy

1. It is False .

2. It can be assumed that the pigments in this plant absorb all wavelengths of the visible light spectrum except blue.
