The energy is dependent on the reactants.
probably the sunlight.............................!!!!!!!!!!!!!!!!!!!
Proteins that reduce the amount of energy needed to start a chemical reaction are called enzymes. Enzymes act as catalysts by lowering the activation energy required for a reaction to occur, thus speeding up the reaction.
During light dependent reactions chlorophyll and other light-aborbing molecules capture energy from sunlight.
The purpose of the light dependent reaction is to convert light energy into chemical energy in the form of ATP and NADPH. This process, also known as the light reactions or light-dependent photosynthesis, occurs in the thylakoid membranes of chloroplasts.
The reaction rate is dependent on temperature (increasing the temperature the reaction rate increase) and activation energy.
Changes in temperature can speed up or slow down chemical reactions by affecting the kinetic energy of molecules. Higher temperatures generally increase the rate of reactions by providing more energy for molecules to collide and react. However, extreme temperatures can also denature proteins and disrupt the equilibrium of a reaction.

The carriers of energy formed during the light-dependent reaction are ATP (adenosine triphosphate) and NADPH (nicotinamide adenine dinucleotide phosphate). These molecules carry the energy captured from sunlight and help fuel the light-independent reactions of photosynthesis.

Polar molecules, ions, and large molecules like proteins typically require energy to cross the cell membrane because they cannot diffuse through the hydrophobic lipid bilayer. This process often involves the use of transport proteins or energy-dependent mechanisms such as active transport.
In a photosystem, an enzyme, known as the reaction center, is surrounded by proteins that enhance the absorption of light and transfer energy to it. The reaction center absorbs the light, which is comprised of photons, and then transfers the energy to one of two types of terminal electron acceptors.
