Primary photoevent.
Light reaction takes place. The first step of photosynthesis
Light reactions occur in the cells chloroplast
In the first stage of photosynthesis, specifically during the light-dependent reactions, water molecules are split through a process called photolysis. This results in the release of oxygen and the accumulation of protons (H⁺ ions) in the thylakoid lumen, creating a proton gradient across the thylakoid membrane. This gradient is essential for ATP synthesis as protons flow back into the stroma through ATP synthase, driving the production of ATP.
The light reaction happens in the thylakoid membrane and converts light energy to chemical energy.The dark reaction takes place in the stroma within the chloroplast, and converts CO2 to sugar.
Photolysis of water and formation of energy rich componds
First step is light reaction.It takes place on thylakoid membranes.
On thylakoid membranes
This is called the light phase oh photosynthesis as opposed to the dark phase. During the light phase, photons excite enzymes on the thylakoid. Also can be known as Light-Dependent Reactions
