Detailed explanation-1: -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. For ATP, it is a phosphate atom, and for NADPH, it is a hydrogen atom.

Detailed explanation-2: -ATP and NADPH are two types of protein carriers.

Detailed explanation-3: -The chemical energy that plants use are stored in ATP and NADPH. ATP and NADPH are two kinds of energy-carrying molecules. These two molecules are not only in plants, as animals use them as well.

Detailed explanation-4: -NADP+ functions alongside many enzymes to provide energy to the many reactions in a cell. NADP+ is the used form of NADPH, and must be reduced with more electrons and a hydrogen. This is typically done during photosynthesis in plants, or as part of sugar digestion in animals.

Detailed explanation-5: -The overall function of light-dependent reactions is to convert solar energy into chemical energy in the form of NADPH and ATP. This chemical energy supports the light-independent reactions and fuels the assembly of sugar molecules.
