Can the Calvin Cycle Happen at Night
This is because the process requires reduced NADP which is short-lived and comes from the light-dependent reactions. The Calvin cycle is a dark reaction because it does not need sunlight. The Calvin Cycle Article Photosynthesis Khan Academy In CAM plants the photosynthesis and initial carbon fixation occur at night and a 4-carbon acid is stored in the cells vacuole. . Wheres does the light reaction take place. Though it is called the dark reaction the Calvin cycle does not actually occur in the dark or during night time. Carbon dioxide concentrations decrease at night. What happens during the Calvin cycle. Calvin Cycle can occur during day and night. It is often too cold at night for these reactions to take place. Can photosynthesis as well as respiration occur at the very same time. The reactions of photosynthesis can be divided into two parts each of which takes place in a different part of the chloropla...
