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
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.
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.
What is the role of photosystem ll in the light reactions?
we call it calvin cycle. It is making glucose.
What fills the electron hole in photsystem 1 and 2?
In photosystem 2- water(photolysis) In photosystem 1 - electron from photosystem 2

What happens to electrons when pigments in photosystem absorb lights?
Photosystem's electron travel through the electron transport chain(etc) where ATP is produced and then back to the photosystem. In non-cyclic photophosphorylation, Photosystem II electron then is absorbed by photosystem I, photosystem I electron used to form NADPH and photosystem II gets its electron from photolysis of water. For you unfortunate children using Novanet: They move through an electron transport chain to photosystem 1.
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 is the role of photosystem ll in the light reactions?
we call it calvin cycle. It is making glucose.
What happens before you get measles?
you ll have fever
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 happens when a photon of light hits photosystem 2?
When a photon of light hits photosystem 2, it excites an electron within the reaction center of the photosystem. This electron is then transferred along an electron transport chain, resulting in the generation of ATP and the splitting of water molecules to release oxygen as a byproduct.
Which sentence best describes what happens after sunlight hits photo system 2?
After sunlight hits photosystem 2, it excites electrons within photosystem 2. These electrons are then passed down an electron transport chain to photosystem 1, where they help generate ATP through a series of redox reactions.
What happens in the photosystem protein when it is hit by a photon of light?
When a photosystem protein is hit by a photon of light, it excites an electron within the pigment molecules in the protein. This electron is then passed along a series of molecules in the photosystem, creating a flow of electrons that drives the conversion of light energy into chemical energy in the form of ATP and NADPH.
What are the products of photosystem 2 and photosystem 1?
NADPH
Where does photosystem 2 and photosystem 1 occur?
Photosystem 2 is located in the thylakoid membrane of the chloroplasts, while Photosystem 1 is located downstream from Photosystem 2 in the thylakoid membrane. Both photosystems are important for light-dependent reactions during photosynthesis.
