Splet20. sep. 2016 · Man y biologists honor the scientist, Melvin Calvin, who won a 1961 Nobel Prize for working out this complex set of chemical reactions, naming it the Calvin cycle. The Calvin cycle has two parts. First carbon dioxide is ‘‘fixed’’. Then ATP and NADPH from the light reactions provide energy to combine the fixed carbons to make sugar. SpletFigure 1. Light reactions harness energy from the sun to produce chemical bonds, ATP, and NADPH. These energy-carrying molecules are made in the stroma where carbon fixation takes place. The light-independent reactions of the Calvin cycle can be organized into three basic stages: fixation, reduction, and regeneration.

SpletThe reactions of the Calvin cycle add carbon (from carbon dioxide in the atmosphere) to a simple five-carbon molecule called RuBP. These reactions use chemical energy from NADPH and ATP that were produced in the light reactions. The final product of the Calvin cycle is glucose. Suggest Corrections. SpletIf 54 molecules of CO_2 enter the Calvin cycle, how many molecules of PGAL leave the cycle? Most textbooks clearly explain how the Calvin cycle is dependent upon the products of the light reactions, but the reverse is also true.
