The Calvin Benson cycle use the energy trapped in ATP and NADPH generated by the light reactions to build sugars from CO2. What below is FALSE regarding this sugar-building cycle?
Select one:
a. Initially RuBP is carboxylated by RuBisCo where atmospheric CO2 is captured and put into the cycle.
b. ATP and NADPH generated by the light reactions are used to reduce 3PG to a more energetic/reduced G3P (some of which will be diverted off to build sugar!)
c. More ATP (from the light reactions) are required to regenerate the remaining G3P to RuBP for the initial CO2 fixation
d. In the absence of light, the Calvin Benson cycle will continue to reduce 3PG to G3P indefinitely, but will be unable to regenerate RuBP
e. Photorespiration occurs when Rubisco inadvertantly captures O2 instead of CO2. I this situation, instead of generating two molecules of 3PG, photorespiration results in 1 molecule of 3PG and 1 molecule of a 2 carbon compound called 2PG (2-phosphoglycolate)

D Question 2 During the Calvin Cycle, plants invest 9 molecules of ATP to produce one molecule of G3P. What is the payoff of this? Plants cannot use the ATP produced by the Light Reaction so they invest them in the Calvin Cycle The plant can use the G3P to make cellulose or starch The Light Reaction needs the G3P RuBP provides 15 molecules of ATP so the plant has an excess of ATP
