Photosystem II is a complex of proteins and pigments located in the thylakoid membrane of chloroplasts. It plays a key role in the light-dependent reactions of photosynthesis by capturing and converting light energy into chemical energy in the form of ATP and NADPH. This process involves the splitting of water molecules to release oxygen as a byproduct.
Excited electrons are transferred to an electron transport chain.
Photosystem II is part of Z scheme or light reaction . It captures light , breaks water , produces oxygen , ATP and NADPH .

What molecule absorbs sunlight in photosynthesis?
Photosystem II
Which photosystem is used first in photosynthesis?
Photosystem 2 happens in photosynthesis before photosystem 1. However they are numbered in order of how they were discovered. Photosystem 1 was discovered before photosystem 2. In photosynthesis the order of them is 2 then 1. meaning that photosystem 1 was discovered 1st but photosystem 2 happens 1st in photosynthesis
Water participates directly in the light reactions of photosynthesis by?
Water participates directly in the light reactions of photosynthesis by donating electrons to photosystem II during the process of photolysis. These electrons are used to replace the ones lost by chlorophyll when it absorbs light energy, allowing the photosystem to continue absorbing light and generating ATP and NADPH for the Calvin cycle.
What is photosytem I and II?
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.
Is carbon dioxide a photosystem II outputs?
No, carbon dioxide is not a direct output of Photosystem II in photosynthesis. Photosystem II's primary function is to harvest light energy and use it to split water molecules into oxygen, protons, and electrons. Carbon dioxide is utilized in the Calvin cycle, which occurs in a different part of the chloroplast.
What molecule absorbs sunlight in photosynthesis?
Photosystem II
What is the start of photosynthesis?
pigments in photosystem II absorb light
Which is a produced using the energy from photons hitting photosystem ii?
ATP is produced using the energy from photons hitting photosystem II through the process of photosynthesis.
Which photosystem is used first in photosynthesis?
Photosystem 2 happens in photosynthesis before photosystem 1. However they are numbered in order of how they were discovered. Photosystem 1 was discovered before photosystem 2. In photosynthesis the order of them is 2 then 1. meaning that photosystem 1 was discovered 1st but photosystem 2 happens 1st in photosynthesis
What sequence accurately reflects the flow of electrons in photosynthesis?
In photosynthesis, electrons flow from water molecules to photosystem II, then to photosystem I, and finally to NADP+ ultimately producing NADPH. Along the way, the electrons generate a proton gradient that drives ATP production.
Water participates directly in the light reactions of photosynthesis by?
Water participates directly in the light reactions of photosynthesis by donating electrons to photosystem II during the process of photolysis. These electrons are used to replace the ones lost by chlorophyll when it absorbs light energy, allowing the photosystem to continue absorbing light and generating ATP and NADPH for the Calvin cycle.
How do photosystem 1 and 2 allow the calvin cycle to work?
Photosystem I and Photosystem II are involved in the light reactions of photosynthesis. Photosystem II absorbs light energy to split water molecules and produce ATP, while Photosystem I absorbs light energy to produce NADPH. Both ATP and NADPH are then used in the Calvin cycle to convert carbon dioxide into glucose. Without the products of the light reactions, the Calvin cycle cannot proceed.
How does water participates directly in the light reactions of photosynthesis?
donating electrons to photosystem II
Is photosynthesis a system?
Photosynthesis is not a system. It is a process in plants. It is very important process.Photosynthesis is a process of making sugars from CO2 and water by using light energy. Photosystem I and photosystem II are involved in this process to transfer electrons across the membrane. Photosynthesis occurs in plants algae and certain bacteria.
How many times are electrons energized during photosynthesis?
The thylakoid membrane contains 2 photosytems, known as Photosystem I and Photosystem II. Together, they function to absorb light and transfer energy to electrons.
What is the difference between photosystem one and two?
Photosystem I absorbs light best at a wavelength of 700 nm, while Photosystem II absorbs light best at a wavelength of 680 nm. Photosystem I transfers electrons to reduce NADP+ to NADPH, while Photosystem II replenishes electrons lost in the process of photosynthesis. Both photosystems work together in the light-dependent reactions of photosynthesis to ultimately produce ATP and NADPH.
What is photosytem I and II?
