The photosystem that feeds the electron transport chain and reduces NADP+ is Photosystem II (PSII). When light is absorbed by PSII, it excites electrons, which are then transferred through a series of proteins in the electron transport chain. This process ultimately leads to the reduction of NADP+ to NADPH, a crucial molecule used in the Calvin cycle for photosynthesis. Additionally, PSII plays a key role in splitting water molecules, releasing oxygen as a byproduct.
What else can I help you with?
What happened in photosystem?
Excited electrons are transferred to an electron transport chain.
What connects the two photosystems in the light?
The electron transport chain connects the two photosystems in the light-dependent reactions of photosynthesis. It shuttles electrons between Photosystem II and Photosystem I, generating ATP and NADPH for the Calvin cycle.
Where do electrons get there energy in photosystem 2?
Excited electrons are transferred to an electron transport chain.
What do electrons that are transferred along the membrane from photosystem 2 and 1 use?
The electrons transferred along the membrane from Photosystem II and Photosystem I use a series of protein complexes embedded in the thylakoid membrane called the electron transport chain. This chain consists of proteins that pass the electrons from one to another, ultimately leading to the production of ATP and NADPH which are essential for the light-dependent reactions of photosynthesis.
Electrons from what replace the electrons form photosystem 2 during non cyclic electron flow?
During non-cyclic electron flow, electrons come from water molecules that are split by photosystem II. These electrons replace the ones lost by photosystem II as they are passed along the electron transport chain.
After electrons leave photosystem II they go into an electron transport chain of three protein complexes. Where do they go after that electron transport chain?
They go into photosystem I.
Where do the electrons go after they finish the electron transport chain?
Photosystem I
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 happen to the light energy that is trapped by the chloroplast during the first stage of photosynthesis?
Light energy is not exactly trapped. The light energy excites the electron in the reaction centres of photosystem I and photosystem II. The electron excites and transfers to the electron transport chain ( chain of electron carriers), this produces ATP. Then the electron of photosystem II is transferred by photosystem I and the electron of the photosystem I is used with H+ and NADP to form NADPH. Photosystem II gets back an electron from photolysis of water.
Where do electrons get there energy in photosystem 2?
Excited electrons are transferred to an electron transport chain.
True or false an electron transport chain connects photosystem 1 and photosystem2?
False. The electron transport chain connects the two photosystems in the thylakoid membrane, but it does not directly connect photosystem 1 and photosystem 2. Instead, it shuttles electrons between the two photosystems as part of the light-dependent reactions of photosynthesis.
What do electrons that are transferred along the membrane from photosystem 2 and 1 use?
The electrons transferred along the membrane from Photosystem II and Photosystem I use a series of protein complexes embedded in the thylakoid membrane called the electron transport chain. This chain consists of proteins that pass the electrons from one to another, ultimately leading to the production of ATP and NADPH which are essential for the light-dependent reactions of photosynthesis.
What molecule precedes the electron transport chain of both photo-system you and photo- system II?
The molecule that precedes the electron transport chain in both photosystem I and photosystem II is plastoquinone. Plastoquinone accepts electrons from the reaction center chlorophyll in both photosystems and transfers them to the cytochrome b6f complex to ultimately generate ATP.
