1. Glyceraldehyde 3 phosphate G3P
Energy from ATP and NADPH is used to remove a phosphate group from
3PGA then reduce the diphosphoglycerate (DPGA) to produce the
3-carbon sugar glyceraladehyde-3-phosphate (G3P).
2. The light dependent reaction involves photosystem I and II.

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

Why is it possible for the Calvin cycle to occur in the dark? A. The Calvin cycle uses energy stored previously during the light-dependent reactions of photosynthesis. B. It is not possible for any part of photosynthesis to occur without light. C. None of the products of the light-dependent reactions are involved in the Calvin cycle. D. The Calvin cycle obtains energy from sugars made previously by the light-dependent reactions of photosynthesis.

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...
