In photosynthesis energy from the light reaction to the dark reaction is transferred in the form of:

Explanation

In photosynthesis, the energy from the light reactions is transferred to the dark reactions in the form of NADPH. NADPH is a molecule that carries high-energy electrons produced during the light reactions, and these electrons are used in the dark reactions, also known as the Calvin cycle, to reduce carbon dioxide into glucose and other carbohydrates. ADP is incorrect because it is the breakdown product of ATP and is used to store energy, but it does not carry electrons, so it cannot transfer energy from the light to the dark reactions. AMP is also incorrect because it is a simpler molecule than ATP, inefficient at storing energy, and similarly, it cannot carry electrons needed for the dark reactions. Chlorophyll is incorrect as well because its role is to absorb light energy and drive the light reactions; it does not participate in transferring energy to the dark reactions. Therefore, NADPH is the correct molecule responsible for carrying energy from the light reactions to the dark reactions in photosynthesis.
