Question

Problem 1 The figure below illustrates what happens during the Calvin cycle of photosynthesis. Use this figure to answer the following questions. a. The first part of the Calvin cycle (labeled B on the diagram) is a fixation reaction. The diagram shows that 3 molecules of RuBP (ribulose bisphosphate) are needed for this reaction and 6 3-carbon low energy molecules are eventually formed. Above the diagram, write the complete fixation reaction that occurs, including the other reactant that is needed to produce the 3-carbon low energy molecules. b. The second part of the Calvin cycle (marked C) involves converting 6 low energy 3-carbon molecules to 6 high energy 3 carbon molecules. On the diagram, show the other 2 molecules that come from the light capturing reactions and that are needed to accomplish this reaction and state what each molecule contributes to the reaction. c. In the part of the Calvin cycle marked C, what molecule is being oxidized and what molecule is being reduced. d. The third part of the Calvin cycle is labeled A. Write a short description of what is happening in this part of the Calvin cycle, and state what other molecule is needed as an input to this part of the Calvin cycle.

          Problem 1
The figure below illustrates what happens during the Calvin cycle of photosynthesis. Use this figure to answer
the following questions.
a. The first part of the Calvin cycle (labeled B on the diagram) is a fixation reaction. The diagram shows
that 3 molecules of RuBP (ribulose bisphosphate) are needed for this reaction and 6 3-carbon low
energy molecules are eventually formed. Above the diagram, write the complete fixation reaction that
occurs, including the other reactant that is needed to produce the 3-carbon low energy molecules.
b. The second part of the Calvin cycle (marked C) involves converting 6 low energy 3-carbon molecules to
6 high energy 3 carbon molecules. On the diagram, show the other 2 molecules that come from the
light capturing reactions and that are needed to accomplish this reaction and state what each molecule
contributes to the reaction.
c. In the part of the Calvin cycle marked C, what molecule is being oxidized and what molecule is being
reduced.
d. The third part of the Calvin cycle is labeled A. Write a short description of what is happening in this
part of the Calvin cycle, and state what other molecule is needed as an input to this part of the Calvin
cycle.
