NADPH
Photosystem 1
No. Photosystems I and II are where light-dependent reactions occur, while the Calvin Cycle is where light-independent reactions occur. Photosynthesis begins with Photosystem II, then Photosystem I, then the products from there go to the Calvin Cycle. (yes photosystem II comes before photosystem I)
Photosystem 1
From energy in photons
to make energy-carrier molecules like NADPH Apex
Light from the sun
Photosystem I and Photosystem II are two protein-based complexes found in the thylakoid membrane of chloroplasts in plants, algae, and cyanobacteria. They are involved in the process of photosynthesis, capturing and converting light energy into chemical energy. Photosystem II functions first in the light reactions of photosynthesis, while Photosystem I follows to further harness light energy and produce ATP and NADPH, which are vital for the synthesis of sugars.
After light hits photosystem I, its energy is used to produce NADPH through the process of photochemical reduction. NADPH is an important molecule that plays a key role in carrying and transferring electrons for various metabolic reactions in the cell.

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.
Photosystem 1
In photosystem I, electrons get their energy from the absorption of light by chlorophyll molecules. When light is absorbed, it excites the electrons in the chlorophyll, allowing them to move through a series of electron carriers in the photosystem to generate energy for the production of ATP and NADPH during photosynthesis.
Photosystem 1
From energy in photons
Light-dependent reactions occur in the thylakoid membranes of chloroplasts and require light to produce ATP and NADPH, which are used in the Calvin cycle to produce glucose. These reactions involve the conversion of light energy into chemical energy through the processes of photosystem I and photosystem II, as well as the electron transport chain. Oxygen is also produced as a byproduct of these reactions.
