WebThe Calvin cycle, Calvin-Benson cycle, or Calvin-Benson-Bassham cycle (CBB-cycle) takes place in the stroma of plant chloroplasts. It entails a series of reactions during which carbon dioxide is reduced and sugar precursors are formed, using the chemical energy (ATP and NADPH) captured by the light reactions. WebIt takes place in stroma or cytoplasm, using ATP and NADPH from photosynthesis with CO2 and H2O to produce carbohydrate. Q. The total requirement of ATP & NADPH for each molecule of CO2 fixed & reduced in photosynthesis in the Calvin cycle is: Q. In Calvin cycle, the products of the light reaction (ATP and NADPH) are first utilized in the.

The light reactions employ photons and water to produce NADPH, oxygen, and water. The NADPH may then be utilized to fuel the Calvin cycle, which generates energy by using the energy stored in ATP and NADPH during light reactions. chris matthews phil donahue

"WebThe Calvin cycle is the cycle of chemical reactions performed by plants to “fix” carbon from C O 2 into three-carbon sugars. The photophosphorylation process which results in the movement of the electrons in a cyclic manner for synthesizing ATP molecules is called cyclic photophosphorylation. " - Calvin cycle byjus
