Detailed explanation-1: -Though it is called the “dark reaction", the Calvin cycle does not actually occur in the dark or during night time. This is because the process requires NADPH, which is short-lived and comes from the light-dependent reactions.
Detailed explanation-2: -Light-dependent reactions happen in the thylakoid membrane of the chloroplasts and occur in the presence of sunlight. The sunlight is converted to chemical energy during these reactions. The chlorophyll in the plants absorb sunlight and transfers to the photosystem which are responsible for photosynthesis.
Detailed explanation-3: -The light-independent reactions (Calvin cycle) use stored chemical energy from the light-dependent reactions to “fix” CO2 and create a product that can be converted into glucose.
Detailed explanation-4: -The Calvin cycle is the light-dependent stage of photosynthesis and occurs in the thylakoid membrane.
