How Does The Carbon Cycle Affect Humans? Humans interac...
The light reactions provide ATP and NADPH to the carbon fixation step of the Calvin cycle, and the Calvin cycle provides water and electrons to the light reactions. The light reactions supply the Calvin cycle with CO2 to produce sugars, and the Calvin cycle supplies the light reactions with sugars to produce ATP.
The Calvin cycle reactions can be divided into three main stages: carbon fixation, reduction, and regeneration of the starting molecule.
33. What happens during the reduction stage of the Calvin Cycle (light-independentreactions)? … Energy from ATP and electrons from NADPH are used to reduce 3-phosphoglycerate to form G3P molecules (which can be used to form other organic molecules such as glucose).
What two molecules produced during the light-capturing reactions of photosynthesis are used in the Calvin cycle? NADPH and ATP. These two molecules are produced in the light-capturing reactions of photosynthesis and are used to provide energy and reducing power to convert carbon dioxide into sugar.
Which of these molecules contributes to the energy that is stored in carbohydrate during the Calvin cycle? The products of the Calvin cycle are 3-carbon sugars. In the Calvin cycle, ATP is required to: donate a phosphate group to 3-PGA.
To synthesize one glucose molecule, the Calvin cycle must turn six times. … Explain why a poison that inhibits an enzyme of the Calvin cycle will also inhibit the light reactions. The light reactions require ADP and NADP+, which are not recycled from ATP and NADPH when the Calvin cycle stops.
During the operation of the Calvin cycle, carbon is withdrawn at different places for sucrose and starch synthesis (Stitt, 1997). That is, triose phosphates are exported to the cytosol for conversion into sucrose, whereas fructose-6-phosphate is used for starch synthesis.
