What happens in the photosystem 2?
Photosystem II obtains replacement electrons from water molecules, resulting in their split into hydrogen ions (H+) and oxygen atoms. The oxygen atoms combine to form molecular oxygen (O2), which is released into the atmosphere. The hydrogen ions are released into the lumen.
What is the function of photosystem II and photosystem I?
During this process, the water-splitting and oxygen-evolving reaction is catalyzed by photosystem II (PSII), while photosystem I (PSI) generates the reducing power for the reduction of NADP+ to NADPH.
What is produced in photosystem 2 quizlet?
Photosystem II produces a proton gradient that drives the synthesis of ATP.
Where is photosystem 1 and 2 located?
Two types of photosystems, photosystem I (PSI) and photosystem II (PSII), are found in the thylakoid membrane inside the chloroplast. Each photosystem consists of multiple antenna proteins that contain a mixture of 300–400 chlorophyll a and b molecules, as well as other pigments like carotenoids.
What is the difference between Photosystem I and Photosystem II quizlet?
What is the difference between Photosystem II and Photosystem I? Photosystems II and I have different chlorophylls. PS II has P680 and PS I has P700.
What is the role of photosystem II in the light dependent phase of photosynthesis?
Light absorption in PSII. When light is absorbed by one of the many pigments in photosystem II, energy is passed inward from pigment to pigment until it reaches the reaction center. There, energy is transferred to P680, boosting an electron to a high energy level.
Where is ps2 located?
thylakoid membrane
So, the correct answer is ‘Inner side of thylakoid membrane’
What is the main product of photosystem 2?
Photosystem II is the first membrane protein complex in oxygenic photosynthetic organisms in nature. It produces atmospheric oxygen to catalyze the photo-oxidation of water by using light energy. It oxidizes two molecules of water into one molecule of molecular oxygen.
