Electrons from what replaces the electrons from photosystem 2 during noncyclic electron flow?
water
What is the explanation for the pathway of electron transport chain?
The electron transport chain is a series of protein complexes and molecules embedded in the inner mitochondrial membrane. It facilitates the transfer of electrons from NADH and FADH2 to oxygen, generating ATP through oxidative phosphorylation. This process creates a proton gradient that is used to drive ATP synthesis.
Is the energy from sunlight trapped by chlorophyll located in the electron transport chain?
No, the energy trapped by chlorophyll is located in photosystem I and II. Light energy is first captured by PS II and an electron is then transferred to a primary electron acceptor known as plastoquinone. Pq then transfers it's electron to the cytochrome complex that transfers its energy to the electron transport system which passes it on to plastocyanin which in turn gives its electron to PS I where it is re-excited by photons. This process is known as the electron transport but the energy captured by chlorophyll is located in the photosystems.
Do the energized electrons at the primary electron acceptor flow to the reaction center?
Yes, energized electrons at the primary electron acceptor flow to the reaction center of photosystem I or II in the process of photosynthesis. This movement of electrons is essential for the conversion of light energy into chemical energy in the form of ATP and NADPH.
How do electrons gain energy in photosystem I?
They absorb photons.
An electron transport chain connects photosystem1 and photosystem2?
They return to Photosystem I
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.
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.
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
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.
What happened in photosystem?
Excited electrons are transferred to an electron transport chain.
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.
What happens to electrons when pigments in photosystem II absorbs light?
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.
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.
