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 the citric acid cycle and the Calvin cycle are metabolic pathways found in living organisms. They both involve a series of chemical reactions that help in the production of energy or organic compounds. While the citric acid cycle occurs in the mitochondria and is involved in cellular respiration, the Calvin cycle takes place in the chloroplasts and is involved in photosynthesis.

In what way is the Calvin Cycle dependent on the first stage of photosynthesis?

The Calvin Cycle is dependent on the first stage of photosynthesis because it relies on the products of the light-dependent reactions, such as ATP and NADPH, to power the conversion of carbon dioxide into glucose.

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.


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.


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. *
