light reactionthe photochemical phase of photosynthesis in which light energy is converted and stored biochemically in the form of ATP
Photosynthesis converts light energy from the sun into chemical energy stored in glucose molecules. This process involves the conversion of light energy into chemical energy, making it an energy conversion reaction.
The conversion of chemical energy into thermal energy through combustion is a common example. Burning wood or gasoline releases the stored chemical energy in the form of heat and light energy.
Bright colors can absorb more light energy, leading to increased activation of molecules in a chemical reaction. This higher energy input can accelerate the reaction rate by providing the necessary activation energy for the reaction to occur. Bright colors may also increase the efficiency of light absorption and conversion to chemical energy, boosting the reaction rate.
The layer that absorbs excess light in photosynthesis is the photosystem. It consists of pigments like chlorophyll that capture light energy and transfer it to the reaction center for conversion into chemical energy.
The light reaction produces ATP and NADPH, which are needed to fuel the dark reaction. The dark reaction (Calvin Cycle) uses the ATP and NADPH produced in the light reaction to fuel the conversion of carbon dioxide into glucose. In essence, the light reaction provides the energy source that drives the dark reaction.

In a glow stick, chemical energy is converted into light energy through a chemical reaction. When the chemicals inside the glow stick mix together, they undergo a reaction that releases energy in the form of light.
The energy conversion that occurs in the burning of a matchstick is chemical energy being converted into heat and light energy. When the matchstick is ignited, the stored chemical energy in the match head is released through a chemical reaction, producing heat and light as byproducts.

The pigment molecule that transfers electrons during the light reaction is chlorophyll. Chlorophyll absorbs light energy and transfers electrons to the reaction center of the photosystem, initiating the flow of electrons through the electron transport chain. This process is essential for the conversion of light energy into chemical energy during photosynthesis.
During the light reaction of photosynthesis, ATP is produced through a process called photophosphorylation. This process involves the conversion of light energy into chemical energy, which is used to add a phosphate group to ADP, forming ATP. This ATP is then used as an energy source for the dark reaction of photosynthesis, where carbon dioxide is converted into glucose.
To provide ATP and NADPH to drive the next part of photosynthesis, the Calvin Cycle (AKA Dark Reaction, Light Independent Reaction). Light reactions also produce oxygen gas as a byproduct.
When a candle burns, the chemical energy stored in the wax is converted into heat and light energy through a combustion reaction. The wax is oxidized (burned) by oxygen in the air, releasing energy in the form of heat and light.
