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 fills the electron hole in photsystem 1 and 2?
In photosystem 2- water(photolysis) In photosystem 1 - electron from photosystem 2
What Photosystem is older in terms of evolutionary history?
Photosystem II is older in terms of evolutionary history compared to Photosystem I. Photosystem II is thought to have evolved before Photosystem I as it evolved to oxidize water in order to provide electrons for the electron transport chain, which Photosystem I then uses to reduce NADP+ to NADPH.
After sunlight hits photosystem 2 what is the best description of what happens?
solar energy changes adp into atp.
What is a role of photosystem 2 in light reactions?
Photosystem two produces O2, ATP, and NADP+

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.
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.
What happens to electrons when pigments in photosystem II absorbs light?
they move through an electron transport chain to photosystem 1
What happens when light strikes a photosystem?
When light strikes a photosystem, it excites electrons in the chlorophyll molecules within the photosystem. These energized electrons are then passed through a series of electron carriers, generating a flow of electrons that drives the conversion of light energy into chemical energy in the form of ATP and NADPH. This process is called photophosphorylation and is a key step in photosynthesis.
What fills the electron hole in photsystem 1 and 2?
In photosystem 2- water(photolysis) In photosystem 1 - electron from photosystem 2
What Photosystem is older in terms of evolutionary history?
Photosystem II is older in terms of evolutionary history compared to Photosystem I. Photosystem II is thought to have evolved before Photosystem I as it evolved to oxidize water in order to provide electrons for the electron transport chain, which Photosystem I then uses to reduce NADP+ to NADPH.
What happens in the photosystem when it is hit by a photon of light?
When a photon of light hits the photosystem, it excites an electron in the reaction center of the photosystem. This electron is then passed along a series of proteins called the electron transport chain, generating ATP and reducing power in the form of NADPH. These energy carriers are used in the light-dependent reactions of photosynthesis to convert carbon dioxide into glucose.
