What happens to electrons when pigments in photosystem II absorbs light?
they move through an electron transport chain to photosystem 1
Where do electrons get their energy in photosystem II?
From energy in photons
Which sequence accurately describes the flow of electrons in photosynthesis?
In photosynthesis, electrons flow from water to photosystem II, then to photosystem I, and finally to NADP+ to produce NADPH. This flow of electrons is facilitated by the electron transport chain within the thylakoid membrane of the chloroplast.
Why do NADH and FADH2 donate electrons to different electron transport chain complexes?
NADH and FADH2 donate electrons to different complexes in the electron transport chain because they have different energy levels and transfer electrons at different points in the chain, allowing for efficient energy production through the generation of a proton gradient.
An electron transport chain connects photosystem1 and photosystem2?
They return to 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 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.
Where do the electrons go after they finish the electron transport chain?
Photosystem I
What happened in photosystem?
Excited electrons are transferred to an electron transport chain.
What is Electron Transport Systems?
The electron transport system is a series of protein complexes and molecules in the inner mitochondrial membrane that transfer electrons from electron donors to electron acceptors, generating ATP in the process. This process is crucial for cellular respiration and energy production in aerobic organisms.
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 to electrons when pigments in photosystem II absorbs light?
they move through an electron transport chain to photosystem 1
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.
How do electrons gain energy in photosystem I?
They absorb photons.
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.
Where do electrons get there energy in photosystem 2?
Excited electrons are transferred to an electron transport chain.
Where do electrons get their energy in photosystem II?
From energy in photons
