The term "light reaction" does not really apply when speaking of mitochondria. Mitochondria are like furnaces. You put the wood in, light it, and it gives off heat. You put glucose into the mitochondria and the membranes facilitate the breakdown of that glucose to release the energy that was trapped in the carbon bonds. That energy is now stored as ATP.
Mitochondria do not store energy, just as a furnace doesn't store heat. They process the fuel (glucose) to release energy--day or night.
"Light reaction" is more aptly applied to photosynthesis, which does depend on light energy for the first part of the reaction.
What else can I help you with?
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.
Where is the energy from light stored after light reactions?
The energy from light is stored in the form of chemical energy in the molecules ATP and NADPH, which are produced during the light reactions of photosynthesis. These molecules then power the calvin cycle to produce sugars.
What is converted in both the mitochondria and the chloroplasts?
Energy is converted in them.In mitochondria chemical energy is kept as chemical enery but carrier changed.In chloroplast light energy stored as chemical energy.
What takes place in the mitochondria and chloroplasts?
Mitochondria are responsible for generating energy in the form of ATP through cellular respiration, while chloroplasts are involved in photosynthesis, where they convert light energy into chemical energy stored in glucose. Both organelles have their own DNA and are thought to have originated from endosymbiotic events in the evolution of eukaryotic cells.
Do chloroplast and mitochondria convert chemical energy?
Chloroplast convert light energy. Mitochondria convert chemical energy itself

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.
