What else can I help you with?
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 their in photosystem I?
From energy in photons
Where do electrons get their get their energy in photosystem?
From energy in photons
How photosystem I and II replenish its lost electrons?
Splitting of water molecules
What happened in photosystem?
Excited electrons are transferred to an electron transport chain.
Where do electrons get their energy in photosystem II?
From energy in photons
How many times are electrons energized during photosynthesis?
The thylakoid membrane contains 2 photosytems, known as Photosystem I and Photosystem II. Together, they function to absorb light and transfer energy to electrons.
What sequence accurately reflects the flow of electrons in photosynthesis?
In photosynthesis, electrons flow from water molecules to photosystem II, then to photosystem I, and finally to NADP+ ultimately producing NADPH. Along the way, the electrons generate a proton gradient that drives ATP production.
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.
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 I?
In photosystem I, electrons get their energy from the absorption of light by chlorophyll molecules. When light is absorbed, it excites the electrons in the chlorophyll, allowing them to move through a series of electron carriers in the photosystem to generate energy for the production of ATP and NADPH during photosynthesis.
Electrons from what replace the electrons from photosystem 2 during noncyclic electron flow?
water
Where do the electrons needed by the water-splitting photosystem originate?
The electrons needed for water-splitting in the photosystem originate from the splitting of water molecules during the light-dependent reactions of photosynthesis. Water molecules are split into oxygen, protons, and electrons by the photosystem II enzyme, providing the electrons needed to drive the electron transport chain.
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.
Where do electrons get there energy from photostem 2?
Electrons in photosystem II get their energy from sunlight. When photons from sunlight are absorbed by the chlorophyll molecules in the photosystem, the energy is transferred to electrons, allowing them to become excited and drive the process of photosynthesis.
Where do the electrons go after they finish the electron transport chain?
Photosystem I
