Generally speaking, the requirement to "start" the Calvin cycle is darkness. Remember that the first step of the first stage (or production phase, where three molecules of Ribulose-5-phosphate, or Ru5P, react with three molecules of CO2 to yield six molecules of glyceraldehyde-3-phosphate, or GAP, at the expense of nine ATP and six NADPH molecules) is the phosphorylation of Ru5P by a phosphoribulokinase to form ribulose1,5-bis-phosphate (RuBP).
The main purpose of plants' Calvin Cycle, occurring in chloroplasts, is to incorporate CO2 into carbohydrates, mainly to form glucose, by means of the ATP and the NADPH from the light reaction of photosynthesis.

What does light dependent reactions supply the Calvin cycle with?
Light reactions provide ATP and NADPH to the Calvin Cycle, and the cycle returns ADP, Pi, and NADP+ to the light reactions.ATP and NADPH are produced by the light reactions of photosynthesis and consumed by the Calvin cycle.
Does the Calvin cycle Requires CO2?
The Calvin Cycle is a light-independent cycle, but it does not require darkness. although it can use light again it does not require it.
What is silmilar between the citric acid cycle and the Calvin cycle?
Both cycles recycle the molecule needed for the first reaction.Both recycle the molecules needed so that they can occur again. Energy is required for both to occur.
How does the purpose of the Krebs cycle differ from the purpose of the Calvin cylce?
The Krebs Cycle's purpose is to produce ATP that cells can use, occurs in animal cells. The Calvin Cycle is in chloroplasts and is used to produce glucose for cells. *
What molecule is the reactant in the first step and the final product in the fourth step of the Calvin Benson Cycle?
RuBP

PGA is the first stable product of?
PGA is the first stable product of The Calvin Cycle of photosynthesis.
Which molecule is a reactant in the first step in the final product in the first step of the Calvin-benson cycle?
RuBP
Are PS I and PS II part of the Calvin cycle?
No, PS I and PS II are part of the first stage of photosynthesis, the light reactions. The Calvin cycle is the second stage of photosynthesis and does utilize the photosystems.
Which molecule is a reactant in the first step and a final product in the fourth step of the Calvin Benson Cycle?
RuBP, ribulose bisphosphate.But, you may be looking for glyceraldehyde-3-phosphate as the answer as it is a product of the Calvin cycle.
What events occur during the Calvin cycle?
The Calvin Cycle has 3 series of reactions. They are Carbon Dioxide fixation, Carbon dioxide reduction, and regeneration of the first substrate RuBP ( ribulose 1,5 bisphosphate). It also produces ATP. Glucose is its outcome which is G3P (glyceraldehyde-3-phosphate).

Which molecule is a reactant in the first step and a final product in the step of the Calvin benson cycle?
RuBP
What is the first step of Calvin-benson cycle?
Carbon dioxide and RuBP combine to make PGA
What molecule is a reactant in the first and a final product in the fourth step of the Calvin-Benson cycle?
RuBP
