It's photosystem II, in the electron transport chain of photosynthesis where light is used to create O2 and H.

Photosystem II is a protein complex in plants and algae that is essential for the process of photosynthesis. It absorbs light energy and uses it to drive the transfer of electrons from water to plastoquinone. This eventually leads to the production of ATP and NADPH, which are important energy carriers used in the Calvin cycle to convert carbon dioxide into sugar.

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.
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
Which is a role of photosystem 11 in the light reactions?
Photosystem II plays a role in absorbing light energy and initiating the process of photosynthesis by passing electrons through the electron transport chain. It also splits water molecules to release oxygen as a byproduct.
What is a role of photosystem 2 in light reactions?
Photosystem two produces O2, ATP, and NADP+
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 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 protein complex absorbs in energy that used to produce NADPH?
Photosystem 1
Which photosystem most likely envolved first?
Photosystem II most likely evolved first because it provides the energy for producing ATP and passes its electrons to photosystem I.
Which is a role of photosystem 11 in the light reactions?
Photosystem II plays a role in absorbing light energy and initiating the process of photosynthesis by passing electrons through the electron transport chain. It also splits water molecules to release oxygen as a byproduct.
What is a photosystem - definition?
A Photosystem is a funnel shaped cluster of photosynthetic pigments, in the thylakoid membrane of the chloroplast.
What is a role of photosystem 2 in light reactions?
Photosystem two produces O2, ATP, and NADP+
Which steps occur in photosystem II?
ADP takes on energy and a phosphate to produce ATP in photosystem II.
