co2,ATP, and NADPH
The Calvin cycle is completed when the cycle of chemical reactions converts carbon dioxide into glucose. This process requires the input of ATP (adenosine triphosphate) and NADPH (nicotinamide adenine dinucleotide phosphate), which provide the energy needed to drive the reactions. The final step of the Calvin cycle regenerates the molecule needed to start the cycle again.
RuBP
Light, carbon dioxide, and water are the materials needed to start photosynthesis. The carbon dioxide is needed for the Calvin cycle while the light and water are required for the light reactions.
6 cycles are required if you consider or start from 1 CO2 , but 2 cycles if you start from 3 CO2 .
The 3 carbon compounds that do not leave the Calvin cycle are recycled back into the cycle to regenerate RuBP (Ribulose-1,5-bisphosphate) for further carbon fixation. This recycling process ensures the efficient use of carbon for photosynthesis.
Calvin would start screaming like hell!!!
People needed a way to measure things
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.
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. *
