Thus, it is also a difference between photosystem 1 and photosystem 2. Moreover, a further difference between photosystem 1 and photosystem 2 is that the PS I is rich in chlorophyll-a pigments while PS II is rich in chlorophyll b pigments. Also, one important difference between photosystem 1 and photosystem 2 is the photolysis process.
Furthermore, photosystem I is present in the outer surface of thylakoid membranes while photosystem II is present in the inner surface of the thylakoid membranes. Therefore, this is also a significant difference between photosystem 1 and photosystem 2.
Below infographic on the difference between photosystem 1 and photosystem 2 provides more information on these differences. Photosystem I and Photosystem II are two major photosystems that carry out light-dependent reactions of photosynthesis in plants. Thus, this is the summary of the difference between photosystem 1 and photosystem 2. Available here 2. Available here. Your email address will not be published.

This system is involved in both cyclic photophosphorylation. Photolysis No photolysis occur. Photolysis occurs in this system. The ratio of the chlorophyll carotenoid pigments Photosystem I or PSI is located in the thylakoid membrane and is a multisubunit protein complex found in green plants and algae. The first initial step of trapping solar energy and the then conversion by light-driven electron transport.
PS I is the system where the chlorophyll and other pigments get collected and absorb the wavelength of light at nm. It is the series of reaction, and the reaction center is made up of chlorophyll a, with the two subunits namely psaA and psaB. This system also consists of the chlorophyll a, chlorophyll a, chlorophyll a, chlorophyll b, and carotenoids. The absorbed photons are carried into the reaction center with the help of the accessory pigments.
Chlorophyll A is the active reaction center of photosystem 2. What is Photosystem 1 — Definition, Characteristics, Function 2. What is Photosystem 2 — Definition, Characteristics, Function 3. What is the difference between Photosystem 1 and 2. PS I is the collection of pigments of chlorophyll, absorbing mostly the wavelength of light at nm. The final stage of the light reaction is catalyzed by PS I. The reaction center of PS I consists of chlorophyll A Photons from light are absorbed by accessory pigments and passed into the reaction center.
Reaction center itself is capable of absorbing photons. The energy of absorbed photons is released from the reaction center as high energy electrons. A schematic diagram of a photosystem is shown in figure 1. Figure 1: A photosystem 1 — Sunlight, 2 — Pigments, 3 — Reaction center, 4 — high energy electron flow, 5 — photosystem.
