Where do electrons come from and how it gains energy during the light reaction?
They come from Photosystem ll. Photosystem ll gets them by ripping the electrons off of water by a process called photolysis. Electrons gain energy first in Photosystem ll, then later in photosystem l, through the absorption of energy from light.
Which is a role of photosystem ll in the light reactions?
Photosystem II (PSII) plays a crucial role in the light reactions of photosynthesis by capturing light energy and using it to energize electrons. This process initiates the photolysis of water, splitting it into oxygen, protons, and electrons. The energized electrons from PSII are then transferred to the electron transport chain, ultimately contributing to the synthesis of ATP and NADPH, which are essential for the Calvin cycle. Additionally, PSII helps to replenish its lost electrons by extracting them from water molecules.
What happens to electrons when pigment in photosystem ll absorb light?
When pigments in Photosystem II absorb light, the energy excites electrons, raising them to a higher energy state. This energized electron is then transferred to a primary electron acceptor, initiating a series of redox reactions in the electron transport chain. This process ultimately leads to the synthesis of ATP and NADPH, which are crucial for the Calvin cycle in photosynthesis. As a result, Photosystem II plays a vital role in converting light energy into chemical energy.
Which is a role of photosynthesis ll in the light reactions?
Photosystem II (PSII) plays a crucial role in the light reactions of photosynthesis by capturing light energy and using it to energize electrons. This process involves the splitting of water molecules (photolysis), releasing oxygen as a byproduct and providing electrons to replenish those lost by the chlorophyll. The energized electrons then move through the electron transport chain, contributing to the production of ATP and NADPH, which are essential for the Calvin cycle. Overall, PSII initiates the flow of energy that drives the photosynthetic process.
What happens when light hits the pigment in photosystem ll?
When light hits the pigment in Photosystem II, it excites electrons within the chlorophyll molecules, raising them to a higher energy state. This energy is then used to split water molecules (photolysis) into oxygen, protons, and electrons. The excited electrons are transferred through a series of proteins in the thylakoid membrane, initiating the process of photosynthesis and ultimately contributing to the production of ATP and NADPH. This occurs during the light-dependent reactions of photosynthesis.

Which is produced using energy from photons hitting photosystem ll?
ATP and NADPH are produced using energy from photons hitting photosystem II. These molecules are essential in the light-dependent reactions of photosynthesis to drive the production of sugars.

What happens when a photon of light hits photosyestem ll?
When a photon of light hits photosystem II, it excites an electron in the reaction center of the photosystem. This electron is then passed along a series of proteins in the electron transport chain, creating a flow of electrons that drives ATP production through chemiosmosis. Additionally, the photon splitting water molecules into oxygen, protons, and electrons, which is essential for the plant to produce oxygen and obtain electrons to replace the excited ones.
What are produced during the light reactions of photosynthesis?
during a light reaction two things are responsible for producing a reaction containing the 5 elelments responsible for these reaction. First and foremost an wavelength supplied by a DC current in other words what comes in and out of the friction of the wave... to be made from the original source one is then able to determine what is beiong produced by the actual current. Your question is fundamentally flawed in the fact that you have not stated the acvtual source of the light in which comes forth from. Are we talking about gas? are we talking about electromagnetisis? Or is it aq simple halogen light that you speak of? In order to assist you further I must know more information, you must restate your question in the form that would indicate about which light source youi speak of.. much like i could ask what comes out of the exhaust fromn a car.....One would Argue that well of couse exhaust fumes do,.... but what if i were speaking in terms of the car i was describing was electric? that being said please try to state your questions clearer in the future and i may be willing to answer them
Where do electrons get their energy on photosystem ll?
In Photosystem II (PSII), electrons receive their energy primarily from photons of light absorbed by chlorophyll and accessory pigments. When light is absorbed, it excites electrons in the chlorophyll molecules, raising them to a higher energy state. This energized electron is then transferred through a series of proteins in the electron transport chain, ultimately contributing to the synthesis of ATP and NADPH during photosynthesis. Additionally, water molecules are split (photolysis) to replenish the electrons lost by chlorophyll, releasing oxygen as a byproduct.
Which molecule is split in photosystem ll?
In photosystem II, water (H₂O) is the molecule that is split during the process of photolysis. This reaction produces oxygen (O₂), protons (H⁺), and electrons, which are essential for the photosynthetic process. The electrons generated from water are then transferred to the electron transport chain, ultimately contributing to the production of ATP and NADPH.
What is a reactant in the process powered by sunlight hitting photosynthesis ll?
In photosynthesis, particularly in Photosystem II, the primary reactant powered by sunlight is water (H₂O). When sunlight strikes Photosystem II, it energizes electrons, leading to the splitting of water molecules into oxygen, protons, and electrons. This process ultimately contributes to the formation of ATP and NADPH, which are essential for the subsequent stages of photosynthesis.
