It is the pigment. It emits electrons after exited.
Light reaction takes place. The first step of photosynthesis
Photosynthesis primarily occurs in the thylakoid membranes inside chloroplasts. However, some preliminary reactions take place in the stroma, which is the fluid-filled region within the chloroplast. Overall, photosynthesis is a multi-step process that involves various parts of the chloroplast.
Rubisco is most active in the stroma of chloroplasts, which is where the Calvin cycle takes place. Rubisco's main function is to catalyze the first step of carbon fixation in photosynthesis, converting carbon dioxide into organic molecules.

It is the second step of photosynthesis. It does not need light
The second step in photosynthesis is the light-dependent reactions, which take place in the thylakoid membranes of the chloroplasts. During this step, light energy is absorbed by chlorophyll and water molecules are split, releasing oxygen as a byproduct. This process generates ATP and NADPH, which are used in the Calvin cycle to produce glucose.

The second step of photosynthesis happens between the chloroplasts, rather than inside of them. This particular step is also independent of light, so if the light suddenly goes away for some reason, it doesn't totally stop the photosynthesis all at once.
When an excited electron is passed to an electron acceptor in a photosystem, it creates an electron transport chain that helps generate energy in the form of ATP and NADPH through a series of redox reactions. This process is a crucial step in photosynthesis that ultimately contributes to the production of glucose and other organic molecules.
