Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
In the Calvin cycle energy stored during the light dependent reactions in ATP and NADPH is
A
Stored in the bonds of sugar molecules
B
Released in to the atmosphere
C
Returned to the soil
D
Destroyed
Explanation: 

Detailed explanation-1: -Overview of the Calvin cycle This process is fueled by, and dependent on, ATP and NADPH from the light reactions. Unlike the light reactions, which take place in the thylakoid membrane, the reactions of the Calvin cycle take place in the stroma (the inner space of chloroplasts).

Detailed explanation-2: -Some Calvin cycle reactions require ATP (adenosine triphosphate), a compound that functions in energy transfer, and NADPH (reduced nicotinamide adenine dinucleotide phosphate), a source of hydrogen atoms for reduction reactions. ATP and NADPH are formed during light-energized reactions of photosynthesis.

Detailed explanation-3: -Light-dependent reactions harness energy from the sun to produce ATP and NADPH. These energy-carrying molecules travel into the stroma where the Calvin cycle reactions take place.

Detailed explanation-4: -ATP and NADPH produced by the light-dependent reactions of the photosystems are used by the Calvin cycle in the stroma of the chloroplast.
