Detailed explanation-1: -ATP and NADPH produced by the light-dependent reactions of the photosystems are used by the Calvin cycle in the stroma of the chloroplast.

Detailed explanation-2: -The net effect of these steps is to convert light energy into chemical energy in the form of ATP and NADPH. The ATP and NADPH from the light-dependent reactions are used to make sugars in the next stage of photosynthesis, the Calvin cycle.

Detailed explanation-3: -The overall purpose of the light-dependent reactions is to convert solar energy into chemical energy in the form of NADPH and ATP. This chemical energy will be used by the Calvin cycle to fuel the assembly of sugar molecules.

Detailed explanation-4: -The sources of energy in the Calvin cycle are Adenosine triphosphate (ATP) and Nicotinamide adenine dinucleotide phosphate hydrogen (NADPH) which are formed during the light reaction in the thylakoid membrane.

Detailed explanation-5: -Generating an Energy Carrier: ATP In the light-dependent reactions, energy absorbed by sunlight is stored by two types of energy-carrier molecules: ATP and NADPH. The energy that these molecules carry is stored in a bond that holds a single atom to the molecule.
