What reactions convert light energy to chemical energy?
The light dependent reactions take in the light energy and convert that to chemical energy, but it is in the Calvin cycle (light independent reactions) where the chemical energy is stored in a complex sugar.
The energy sources needed for the light reactions and the carbon reactions respectively are?
The energy sources needed for the light reactions in photosynthesis are light (photons), which are absorbed by chlorophyll. The energy sources needed for the carbon reactions (Calvin cycle) are ATP and NADPH, which are produced during the light reactions.
What is the primary purpose of the light-dependent portion of the energy synthesis pathway in plants?
The primary purpose of the light dependent portion of photosynthesis is to convert light energy into chemical energy stored in ATP and NADPH, which will then be used in the light independent reactions.
Is light common to both cellular respiration and the light reactions of photosynthesis?
Yes, light is common to both cellular respiration and the light reactions of photosynthesis. In photosynthesis, light energy is used to convert water and carbon dioxide into glucose and oxygen. In cellular respiration, the energy stored in glucose is released through a series of reactions to produce ATP, and light is not directly involved in this process.
Are light rays a form of chemical energy?
The internal energy stored in the chemical bonds between atoms is a form of potential energy that is sometimes called chemical energy. Basically, chemical energy is internal energy stored in the chemical bonds between atoms. Chemical energy is an example of potential energy. Light rays are electromagnetic energy they can be a good example of this is photosynthesis.
What reactions convert light energy to chemical energy?

What happen in the light independent reactions?
Light is absorbed where it is converted into energy via the light reactions. It is then transfered to the Calvin Cycle, where it is used to make stored energy, and the used ATP (energy) units are recycled to the light reactions and the process repeats.
When light is absorbed light energy is transformed into stored energy true or false?
True. When light is absorbed by a substance, the light energy is converted into stored energy within the molecules of the substance. This stored energy can then be used for various processes such as chemical reactions or heat production.
How do the light reactions and dark reactions work together?
The light reactions provide energy carriers for the dark reactions.
What happens in the light reaction?

How do light reactions provide energy for dark reactions?
In photosynthesis, the light reactions converts the sunlight int chemical energy (ATP molecules, NADH+H). Dark reactions (light independent reactions) do not use sunlight directly, but use energy stored in ATP and NADH molecules combined with CO2 to produce sugars.
Where does the energy come from to make NADPHin the light reactant?
The energy to make NADPH in the light reactions of photosynthesis comes from sunlight. Light energy is absorbed by chlorophyll molecules in the chloroplasts of plant cells, which triggers a series of reactions that ultimately produce NADPH.
How do the light provide energy for the dark reactions?
In photosynthesis, the light reactions converts the sunlight int chemical energy (ATP molecules, NADH+H). Dark reactions (light independent reactions) do not use sunlight directly, but use energy stored in ATP and NADH molecules combined with CO2 to produce sugars.

Where is chemical energy stored in matter?
Chemical energy is stored within the bonds between atoms and molecules in matter. When these bonds are broken through chemical reactions, such as combustion, this stored energy is released in the form of heat and light.
Can light provide activation energy?
Yes. Light can provide activation energy. In fact some chemicals must be stored in the dark to prevent unwanted reactions.
How is chemical energy stored?
Chemical energy is stored in the bonds between atoms and molecules. When chemical reactions occur, these bonds are broken and rearranged, releasing or absorbing energy in the form of heat or light. This energy is then stored in the new bonds that are formed.
